#MakeoverMonday 2022 Week 36 - Median Age at First Marriage in America
This was a relatively simple data set and I was able to build quite a few vizzes during Watch Me Viz. I ended up with something more complex that it needed to be, but it was fun figuring out how to create the calculations.
Here's how it works:
- Compare the median age at first marriage of each state to the US average for 2006-2010
- Compare the median age at first marriage of each state to the US average for 2015-2019
- Check whether the State
- Stayed above the US average in both time periods
- Stayed below the US average in both time periods
- Moved from below the US average to above the US average
- Moved from above the US average to below the US average

#MakeoverMonday 2021 Week 30 - America's Racial Breakdown by State
Makeover Monday week 30 looked at this viz from Visual Capitalist showing the percentage of each race in each State in America.
In the video below, you'll see my recreate the tiled treemap before creating a tiled bar chart. Thanks for watching!

#MakeoverMonday Week 27 - If Only _____ Voted
- To see across each metric in order to identify consistent blue or red patterns for an entire demographic (e.g., early voting or urban).
- To see if individual States always voted for Biden or Trump irrespective of the demographic (e.g., CA, MA, MD for Biden or KS, KY, LA for Trump).

- Rank table calculations
- Parameters
- Filter actions
- Padding in dashboards
- Cleaning tooltips
- Divider lines in dashboards

How to Create U.S. Electoral Cartograms
I don't remember how I came across the set of cartograms I'm going to show you how to create. Alas, I wanted to recreate this mesmerising set of cartograms that Noah Veltman created based on election maps from various media outlets.
- X on the Columns
- Y on the Rows (and reverse the axis)
- Set both X and Y to AVG
- Change the mark type to Polygon
- Add the Path field to the Path shelf (this tells table how to connect the edges of the polygon)
- Add the State field to the Detail shelf

Pregnancy, Birth, and Abortion Rates in America
With Amy Coney Barrett being sped through the confirmation process of the US Senate before the 2020 Election (as hypocritical as it was) to become the 9th justice on the Supreme Court, there is now a conservative stranglehold on the judicial branch of government.
Justice Barrett deflected all questions about her stance on abortion during the confirmation process and it has raised lots of speculation that Roe v. Wade will be overturned. Yeah, you know, because the government should control a woman's body, yet there is nothing similar for men. Like, why doesn't a man get castrated if he accidentally impregnates a woman? Blasphemy they say; hypocritical I say.
I wonder if any of the anti-abortion Justice or Congresspeople have ever considered their stance if their daughter had an unplanned pregnancy. What is she got raped and pregnant? I bet their tune would change.
Anyway, my political and social views aside, this made me think about abortion rates in America. Since Roe v. Wade, abortion rates in the US have plummeted.

How to Create Time Series Tile Grid Maps
Unlike traditional maps, tile grid maps allow you to allocate equal space to each geographical area. We've probably all seen hex maps of the United States. Tile Grid Maps are similar, except they are squares with each block being the same shape and size.
In this video, I show you first how to create the tile grid map, then how to overlay time series data. I then show you three different visualization types for the time series. You could easily create bar charts as well.
Enjoy!

Visualizing the Geography of TV Stations
The piece I wanted to replicate in Tableau is based on her beautiful work Visualizing the Geography of FM Radio. Since she had already done this for radio, I thought I'd try to replicate her work, but with TV stations, that is, the strength and coverage that the broadcast signals from TV stations transmit.
First, I had to prep the data. Fortunately the raw data was easily accessible on the FCC website as are explanations of the fields and how to use them. The FCC also have information about which States fall into which FCC regions. I manually grouped the States into their regions in Tableau (it would have needed to be manually created data anyway).
From there, it was some data prep to get the signal boundaries for each state, ensure they are in the correct State (e.g., some stations that were listed in California actually plotted in other States), then export as a TDE (Hyper files don't work well with polygons).
Here's the Alteryx workflow:
For Tableau, I created a custom color palette based on the color legend on Erin's vizzes, replicated her maps as close as possible, and that's it!
Enjoy!

#MakeoverMonday: How have annual wages changed for union vs. non-union employees?
What works well?
- I like the handwriting font. It makes the viz look fun.
- The colors are distinct enough.
- Using shading on the title as a legend
What could be improved?
- Some hands are holding another, some are not. What does that mean? Does two hands mean union? If so, I don't understand why they join where they do.
- Using weekly wages is a tough concept to grasp. Why not convert it to annual wages?
- The viz is clearly not designed for any sort of precision or comparison.
What I did
- I really liked this Viz of the Day recently by Spencer Bauke and thought this was a good data set to try to emulate his work.
- I wanted to use parameter actions to allow the user to change the comparison year.
- I also wanted to use set actions like Spencer did, but this data wasn't structured in a way that made sense to try to do that.
- This turned out to be very good practice for LOD expressions.
- I loved using containers to lay all of this out!! It's a lot of work, but much easier to get everything to line up and all be the same size.

#MakeoverMonday: STD Infection Rates in America 1996-2014
Here's the viz:
Eva had the idea this week to created a discussion on Twitter about what people thought could be improved. For me, it's been a fascinating discussion and it shows how much people participating in Makeover Monday have learned about data visualization. Follow the thread here.
WHAT WORKS WELL?
- Simple title that includes the time frame for context
- Using the subtitle as instruction
- Keep the filters grouped together on the right, out of the way
- Lose the red/green color palette.
- A diverging color palette should only be used if there's a natural midpoint; there isn't one with this data
- There's double encoding on every chart.
- The State filter list it too big; granted though that there was no multi-select dropdown filter at the time.
- The map and the states bar chart are the same.
- The sparklines and the bar charts represent the same data.
- The reference lines aren't needed. What does an average infection rate really mean?
- Simplified the metrics
- Used a map that weights all states equally (like a hex map but circles)
- Used only a single color
- Used highlighting more effectively
- Created simple filter actions
- Used simple chart choices

#MakeoverMonday: More than ever, Americans aren't having sex
What works well?
- Overall, the chart is really good.
- The title and subtitle make it very clear what the viz is about.
- The labels focus you to the topic the creator wants you to focus on.
- I like how the first year is a filled dot and the last year is an open dot.
- Bolding the first and last years on the axis
- Including the % sign on the y-axis for only the top value
- Is this colorblind friendly? I'd recommend verifying.
- Does green mean good?
- I don't know how they came up with the percentages they did. They don't match the source.
- Label the lines directly with their frequency instead of using a color legend.
- Lighten the gridlines.
- Like the original, I filtered out 2012 because the data looks corrupted.
- I liked the original, so I didn't change a whole lot. The main difference was splitting up the frequencies vertically.
- Because I split of the frequencies, I made the viz tall and skinny and mobile friendly.
- I labeled the start and end of each line.
- I labeled the highest value for each frequency.
- I included the change between 1989-2018 on the end of each line as a summary. I had to float everything to make this work, which damaged my soul a bit.
- I'm only displaying the first and last year on the y-axis.
- I included tooltips so the reader can see the exact values.
- I used three shades of a single color that go from least sex to most sex (since the focus is on less sex).
- I kept the same title and subtitle.
- I used fonts from the Washington Post website. NOTE: They won't render on Tableau Public unless you have the same fonts installed (Playfair Display and Yantramanav).

Makeover Monday: How President Trump Spends His Executive Time
- Trump usually spends the first 5 hours of the day in Executive Time.
- He spends his mornings in the residence, watching TV, reading the papers, and responding to what he sees and reads by phoning aides, members of Congress, friends, administration officials and informal advisers.
- Trump doesn't take an intelligence briefing until 11am or 11:30am, and they only last 30 minutes.
What works well?
- Using a color that stands out over the others to highlight executive time
- The title tells me what the viz is about.
- The subtitle provides context as to the amount of data that the chart summarizes.
- Simple labeling
- Including the total time at the bottom and stretching the lines to the ends of the stacked bar chart
What could be improved?
- It's hard to compare the executive time to all other time. A percentage would be helpful.
- Would the stacked chart be better as a horizontal bar chart with two rows?
What I did
- I wanted to look at the frequency of executive time by hour of day and day of week. Does Trump spend the same amount of executive time each day?
RESULT: The first couple heatmaps looked terrible, but visualizing by weekday looks ok. - Do big numbers help tell the story in the data?
RESULT: Yes, they help summarize the data well, but didn't help my end product. - Are there any trends in the data? That is, is executive time increasing or decreasing? Or has it been consistent?
RESULT: The trends are not very useful.

Makeover Monday: Workers Making Minimum Wage or Less in America
What works well?
- Maps are easy to understand
- Positioning of Alaska and Hawaii in the available space
- Including notes about the data in the footer
- Simple, effective title
- Using a single color gradient; a diverging palette would not be appropriate
What could be improved?
- Ranges are not the same size
- Smaller States are nearly impossible to compare; this is a good use case for a hex or tile map
- No context for good vs. bad
What I did
- Looked at the data over time
- Included a comparison to the US average for context
- Included all States for context
- Allowed the user to highlight the State they are interested in
- Included labels on the ends to the lines to show change over the entire period
