A Coronavirus COVID-19 dashboard for the world and each country created by me. There are log y-axis scale plots and normal y-axis scale plots. Also a plot showing trends of each California county – I created this to help understand what tier* each county will be at any given date. Source code is provided below:

California County Tier System Info

California uses a tier system to see what counties can have which businesses open.

This tier system uses positivity rate and daily new cases per 100,000 over 7 day rolling average (also known as moving average). Since the positivity rate lately is very good, I do not consider it in my California county plots. I plotted the daily new cases per 100K with a 7 day moving average. Turns out there is an offset/correction that is applied which I couldn’t figure out.

To see the corrected value check this link (it also explains the tiers):

Additional Info

  • The charts are updated every 6 hours starting at midnight PST. However, the values to the data source are updated daily, so don’t expect new values until after midnight.
