Collects ping latency samples for a list of locations, saves them to disk, and renders plots for an overview and per-location time series.

• Update addresses.json with your locations.
• Install matplotlib in your Python environment.

Example addresses.json:

[
  { "name": "Google DNS", "address": "8.8.8.8" },
  { "name": "Cloudflare DNS", "address": "1.1.1.1" }
]

python3 ping_collect.py --duration 60 --output-dir results

This writes:

• results/ping_samples.json
• results/ping_samples.csv

python3 ping_plot.py --input-json results/ping_samples.json --output-dir results

This writes:

• results/latency_overview.png
• One plot per location named with the name field (e.g., results/Google_DNS.png)
