Hi Mads! I see you're just a short jump up the road in Los Angeles. We are lucky to have such rich sources of data here at the State, County, and Municipal levels. One way to help residents understand it is in terms of how fast it's affecting their population. Here's an example with death rates, but I think you could adapt the idea to infection rates:

Another approach that seems work are charts of actual data with modeled projections - one portraying the current trend and another with a very optimistic trend:

That's a nice source but 56 charts are overwhelming. I wanted to see one or a few counties individually. Digging deeper I saw the counties are Entities so my question is how allow a county to be selected as a user option, text name or otherwise.

I used the functions to retrieve data for my county. Everything worked fine until the recent surge. On a plot of deaths the latest data was not shown but the plot shading was extended from the last point at a constant level. With help from Wolfram support I learned one had to add ,PlotRange -> Full option to DateListPlot. That fixed the problem.
