A US states map polling coronavirus cases reported from Worldometer and the JHU data and also Wikipedia, refreshing every hour (when new data is available). The cases are divided by population of each state to get a per capita estimate. https://us-covid19-per-capita.net
When new data is available, it is updated in data.csv. To download all snapshots of the data run python download.py (going back to March 21). It will get downloaded in a format for example 2020-03-23-13-04.csv which corresponds to the date and time in UTC. The last two numbers are hours and minutes.
All of the snapshots are then added to one file historical.csv. Which looks like this
| states | timestamp | confirmed | deaths |
|---|---|---|---|
| AZ | 2020-04-07 17:07 | 2576 | 73 |
| AZ | 2020-04-07 20:22 | 2851 | 73 |
| CA | 2020-03-21 19:20 | 1249 | 24 |
