A Coronavirus COVID-19 dashboard for the world and each country created by me. There are y-axis-logarithmic plots and y-axis-normal plots. Additionally, there are plots for every state/province/territory for the US and Canada and a plot showing trends of each California county. I created the latter to help understand what tier* each California county will be at any given date (this was applicable prior to June 15th 2021). Each plot is provided with regular raw values, and with values adjusted per population of the considered area (this gives relative information which is more useful then raw numbers when doing comparisons). Source code for everything is provided in the Github link below.

California County Tier System Info

Before June 15th 2021, California used a tier system to see what counties can have which businesses open.

This tier system used 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.
