#MakeoverMonday 2021 Week 15 - Fouls Called by NBA Referees

No comments

The original viz for this week was so good that I struggled to come up with something different. In the end, I wanted to learn by recreating the original. Check out #WatchMeViz and interact with the viz below.

#MakeoverMonday: Ironman World Championship Medalists

No comments
Sunday was the 43rd Iron World Championship. It was the first time I spent a lot of time watching it and I found it pretty cool. I figured I should pay more attention to how it all works given I'm doing Challenge Roth in July. I'm a bit daunted by the prospect of competing in an Ironman distance, but I know I can do it with proper training.

The viz to makeover is a simple table from Wikipedia:


What works well?
  • The years are listed in order from most recent to oldest.
  • Table can be sorted
  • Including separate columns for each medal
  • Including links to each athlete

What could be improved?
  • I'm not convinced that both the flag and country abbreviations are necessary; one is probably enough.
  • Some of the athletes have red text and some have blue. I couldn't find anything on the page that explained this.
  • Comparing athletes across years is difficult because of the precision of the times/

What I did
After exploring the data for a few minutes, I remembered that Rody Zakovich created an incredible viz about the Winter Olympics (check it out here) and I've been wanting to emulate it. This data set proved perfect for it. This is the beauty of Tableau Public; you can download workbooks, see how someone created their work, and use it to help create your own.

Here's my viz for Makeover Monday week 42 (click on the image for the interactive version).

Makeover Monday: How well did The Guardian predict the Premier League table?

3 comments
Back to sports again this week. With the Premier League season just finishing, we're looking at how well The Guardian predicted the EPL table at the start of the season.


What works well?

  • Sorting the teams by prediction makes sense since this is an evaluation of their performance against their prediction.
  • Including the logos so people can find their favorite team
  • Including the numbers for the table position so that the reader doesn't have to count as they go
  • Shading every other row helps break up the view

What could be improved?

  • If you don't know the team logos, it can be hard to track a team across the table.
  • It's hard to see which team did better and worse than expected.
  • There's no scale for how "well" The Guardian predicted the table.

My Goals

  • Focus on the difference between the predicted and actual results
  • Try to create some sort of unit chart (I didn't have time to figure out the calcs, so I cheated with distribution bands)
  • Make it easier to see if team finished above or below the predictions
  • Finish in under an hour because we did MM live at the Data School and had to present to Eva at the end of the hour

Makeover Monday: Toughest Sport by Skill

1 comment
I've had this data set in the queue for probably two years now and it's finally time that I got to post it. I know Eva loves sports data sets (cue eye roll), so this week we're looking at the toughest sport by skill according to a group of sports science experts surveyed by ESPN.


What works well?

  • The sports are ordered by the rank by default, making it easy to see how the compare to other sports.
  • You can sort by any of the column headers.
  • All of the definitions are provided and thoroughly explained.
  • If you need to look up a value, a table works perfectly.

What could be improved?

  • It needs to be easier to see the relative difference between sports.
  • Comparing more than one metric at a time across two sports takes too much brain power (for me at least).
  • Filtering would help make the list more digestible.

My Goals

  • Allow the user to compare two sports, rather than all sports at once.
  • Make the difference between the sports across all of the skills easier to understand.
  • Show which skill is harder/easier when comparing two sports.

Makeover Monday: The 28th SEA Games

No comments
I'm currently on holiday in Tuscany, Italy, so please excuse my brevity this week. In fact, I'm going to admit that I cheated. I reused a viz I did for Makeover Monday last year. I liked it then, I like it now. I don't see any harm in doing this when pressed for time.

Let's have a look at the original viz:


What works well?

  • The different backgrounds for the sections help split apart the viz and inform you that they are to be read independently.
  • It's very informative about the games overall.

What could be improved?

  • The parts are all disjointed.
  • There's no overall story.
  • When I ask "so what?", I can't answer it.

Again, sorry for the brevity this week; I really need to be spending time with my family. Here's my Makeover Monday submission.

Workout Wednesday: NCAA Final Score-by-Score

2 comments
For Workout Wednesday week 21, we look back at an epic NCAA final between North Carolina and Gonzaga.

Here's your challenge:

  • Final dashboard is 700x700
  • Everything must be a single sheet except for the footer
  • Match the title, summary below the title, colors, and tooltips
  • Each circle represents a score
  • Circles are sized by the type of basket (FT, 2Pt, 3pt)
  • Score must be cumulative across the game; note that time counts down in basketball
  • Tooltips should shows the score at that moment in time and a description of what happened
  • UNC color is #6490C6 while the Gonzaga color is #00143F
  • Gridlines should be displayed every 5 minutes and every 10 points
  • Last basket for each team should be labeled with the cumulative score

Download the data here. I think that's it, but if I missed a requirement, let me know and I'll update this post. Good luck!

Makeover Monday: How Different Media Outlets Get Around Saying "Groin"

3 comments

Definitely my quickest Makeover Monday ever. Forgive me, I’m busy at the bar at the beach.

This week we looked at a rather funny dataset from FiveThirtyEight about how the media tries to avoid saying “groin” when someone in a sporting event gets hits where it hurts. They presented their work in this table:


There’s nothing particularly terrible about this other than a table of numbers makes comparisons more difficult than necessary. The summary on the right helps it make a bit more sense.

For my viz, I wanted to create a chart that I’ve never built - a treemap bar chart. Basically this is a way to view the distribution of the words by each media outlet but also summarize them in bar chart form so that you can see which media outlet ranks the highest.

Makeover Monday: Stephen Curry Hates Mid-Range Jump Shots

6 comments


This week's Makeover Monday looks at this simple stacked bar chart from Sports Chart of the Day:


What works well:

  1. Nice labelling on the axes; this makes it clear what we data is displayed
  2. Nice annotation of the point of the chart


What could be done better:

  1. Needs a better title
  2. Needs to incorporate shooting % so that I can better understand the relationship between shots taken and shooting %
  3. Group together all shots over 30 feet
  4. Find a better way to compare the number of shots taken on each range. I find the stacked bars hard to compare within in a shot distance.
  5. Make the different shot ranges more clear, e.g., what defines a long 2?
  6. Provide a summary
  7. How are Curry's shot selections changing over time?


With these considerations in mind, here is my my makeover of the chart:

Philadelphia Has the Worst Sports Teams in North America

I was listening to Sports Radio WIP yesterday as I was driving to get a cup of delicious Dunkin Donuts coffee. I heard one of the hosts talk about how Philly is the worst sports city in all of North America for cities that have teams in all four major sports leagues. A quick Google search turned up this article.

How bad are Philly sports teams?
  • The Eagles are more or less unwatchable. They’re inventing new ways to lose.
  • The 76ers have lost 20+ games in a row. That’s really, really hard to do in the NBA.
  • The Flyers couldn’t score if there was no goalie in the opposing net.
  • The Phillies…well, they did their best to be one of the worst baseball teams of all-time.

I took the ugly table of numbers from the article and built the interactive dashboard you see below, confirming my worst fears.



This merely confirms the misery that is being a Philadelphia sports fan.

Makeover Monday: How Much More Valuable are NFL Franchises than Other Leagues?

A couple weeks ago, Business Insider published a very simple bar chart showing the total value of all franchises for the four major professional sports in the USA. At the Data School, I’m always stressing context in visualisations.

Business Insider’s chart is lacking context, so in today’s makeover, I walk you through a few simple methods for adding context to a simple bar chart.

Makeover Monday: Cristiano Ronaldo is the Most Popular Athlete in the World and it isn't Even Close

No comments
I had a choice to make this evening, catch up on my backlog of Makeover Monday posts or work on my performance review.  Given that I enjoy writing about Tableau more than writing my performance review, allow me to present a second Makeover Monday of the day today.  In this post, I take a look at this chart from Cork Gaines of Business Insider:


I've reviewed a lot of Cork's charts and this one makes many of the same mistakes as his past charts:
  • It's incredibly annoying to have to turn my head sideways to read the chart.
  • The chart is in ascending order, yet the story emphasizes the descending order.
  • The colors aren't distinct enough from each other for me. For example, the colors for Track & Field and Cricket and too similar.
  • The chart, on it's own, doesn't capture the entire story that's in the article.
With these problems in mind, I went to the Facebook page for each athlete and noted their likes.  I then decided to use Tableau's Story Points feature. As Tableau says "Story Points gives the author the ability to present a narrative. As part of that narrative, the author can highlight certain insights and provide additional context."

Makeover Monday: ESPN is biggest reason cable TV isn’t going to die anytime soon

No comments
I'm a HUGE sports fan and love to watch live sports, which means I love ESPN. This also means I'm tied to cable or satellite TV since ESPN does not broadcast online without a subscription. Today's Makeover Monday take a look at ESPN's broadcast rights to major sports.

Consider this simple bar chart by Cork Gaines of Business Insider:


Seems simple enough, right? Simple, yes. But is it 100% truthful? No.
  • I'm not convinced the data is accurate. The rights listed on wikipedia don't align, but you shouldn't assume wikipedia is 100% accurate either.
  • The very first bar bugs me. How can you bucket a bunch of sports into NCAA when each sport has a separate contract?
  • Using a bar chart assumes that all of these contracts started in 2010, which is not the case.
  • This chart shows that the college football playoff contract started in 2010, yet the CFB playoffs don't start until 2015. This is clearly wrong.
I was torn between a couple of alternatives, so I'll show you both of them. If you want the data, you can download it here. You can download the Tableau workbook here.

My first alternative was to make a Gantt chart so that I could see the entire length of the contracts. In this view, I've updated the timeline to go back to 1981.




My second alternative is simply a dot plot view of the original chart. This view keeps the timeline starting at 2010.


Which do you prefer? I'm torn.

Makeover Monday: SEC Football Coaches Get Paid!

5 comments
College football season is nearly upon us and for those that live in the Southeastern US, college football is king. It dominates EVERYTHING - from sports talk to newspapers to online forums to Facebook posts to coaching salaries. College football = Life to so many people. If you've never been to an SEC football game, add it to your bucket list; it's an experience unlike any other.


Saturday Down South is a website dedicated to all things SEC football. This past Thursday, they published this list of the salaries for each coach in the SEC (except for Vanderbilt who does not publish their coach's salary).


This list is simple enough, yet when I saw it, I felt like there was more of a story in there. You can clearly see, just from the table, that Nick Saban is a huge outlier. He's a winner, and he gets paid to win. Keep in mind that these are only their base salaries too. Bonuses, appearance fees, etc. are not included.

I decided to use Tableau's story points for the first time to answer a couple of key questions:
  1. How much of an outlier is Saban compared to his peers in the SEC, to other coaches in other sports and to other college football coaches?
  2. How widespread is this level of pay for college football coaches and how does the SEC stack up?
  3. Is Saban worth the money?
I also need to give a quick thank you to Emily Kund and Matt Francis for reviewing this story for me.

Some things I've learned while using Story Points for the first time:
  • If you want to tell a story, know the questions you want to answer ahead of time. This will help you plan the beginning, middle and end of the story.
  • As I answered questions, I was led to more questions, which led to finding more data, which led to a better story. Be prepared to iterate.
  • Story Points are pretty inflexible. You can't do any formatting of you viz once you're inside the Story Point. You have to go back to the original worksheet to change anything. I had expected this to work more like editing a viz on a dashboard.
  • I feel like I'm not quite using Story Points as they were intended. I feel like I'm missing their intent in this attempt because I could have done all of this same formatting with multiple dashboards and tabs. I need to learn more about the “idea” behind Story Points.

Do you like the NBA? Do you like beer? How much will you have to pay?

2 comments

Business Insider published this vertical bar chart of beer prices in the NBA.  The data is incredibly simple, yet they made the chart unnecessarily hard to read.

Some of the problems I see with this chart include:

  1. The vertical bars should be horizontal, which would make them easier to read and compare.
  2. The bars are sorted backwards.  The topic is high beer prices, so the highest prices should be first.
  3. This chart requires you to turn your head sideways to read it.  When you mentally turn your head, suddenly the chart goes from right to left, instead of left to right.  Bars are easier to compare when left aligned vs. right aligned because that’s how we read. 

I previously had some data from Forbes about franchise values (and other financials).  I added the beer price to the data set.  My goals for this viz were:

  1. Redesign the chart, factoring in the problems I’ve noted
  2. Make the chart a bit more fun
  3. Determine if there’s a relationship between what teams charge and their revenue, franchise value, etc.

Has you wife accused you of putting on a few pounds? Find the exercises that are right for you.

2 comments

Earlier this week, my wife was having a conversation on Facebook about our move to California when she suddenly said “he has gained weight from the cafeteria.”

She’s was being funny.  If you ever meet her, you’ll know what an angel she is quite quickly, especially for putting up with me.

Unfortunately she’s not exactly wrong.  I pretended to be offended of course.

Many of us are familiar with the “freshman 15” from college.  At Facebook, there’s the “Facebook 15”.  Same idea.  I can use the unbelievably tasty, free food and unlimited snacks as an excuse (moderation is a challenge), but I really haven’t gained much weight, maybe five pounds.

I exercise, not often enough however.  I decided that I needed some help, so I build this viz to help me find the right activities for me.

Is drug testing working in baseball? An interactive analysis.

2 comments

Cork Gaines wrote about the HR trend in baseball since testing started for performance enhancing drugs.  He presented a chart of the trend (surprising effective given his past charts), but he never answered his own question….is testing working? 

One way to determine the answer is through comparisons to other statistics.

I downloaded the season averages across both leagues and MLB in total from baseball-reference and built this interactive analysis.  The stats are order by batting stats then pitching stats.

This viz allows you to compare home runs to many other statistics through the selectors at the top right.  In addition you can:

  1. View any two statistics to look for trends by choosing a primary measure and a comparison
  2. Filter the time frame to all years, the pre-testing era, and the testing era (1993+)
  3. Filter the leagues to focus your analysis
  4. Click on a league at the bottom to highlight that league

In this initial view of HR vs. ERA, I see a couple of things:

  1. HR are on a slow descent in the testing era, especially since 2000
  2. ERA is in a similar decline, possibly indicating that improved pitches has had as much of an impact as testing
  3. Batting Average has remained flat.  This means that the reduction in HR has not impacted BA.
  4. Teams are simply scoring fewer runs, likely due to the reduction in long balls
  5. The trend in complete games is despicable

What do you see?  Play around with the different stats and see if you can draw any conclusions.

A 17-slice pie chart is a bit excessive

2 comments

The commentary included with the pie chart below is fantastic, but the pie chart is absolutely horrible.

A simple bar char is much more effective.  With the bar chart, it’s so much easier to see just how favored Ohio State is to win the tournament.  Also, there’s no color legend, therefore you’re not tempted to assume the colors mean something.

With the bar chart, I can clearly see that Florida and UNC are way overrated and Texas is way underrated (the seeds are in parentheses).
