Hi HN,

I couldn't find a richly interactive COVID-19 map anywhere that includes historical data, so I made my own. I used SvelteJS and deck.gl to create a fast and functional frontend. The dataset comes from USAFacts[1].

Source code can be found here: https://github.com/freedmand/covid19map

Here's a map from Johns Hopkins: https://coronavirus.jhu.edu/map.html

I've definitely seen/used that map, which as far as I know is one of the authoritative ones worldwide. I wasn't able to see how to paginate back in time with that map to view growth, which was one of my primary motives for building this one. Is there a way to do that with the John Hopkins map?

One very useful metric would be the percentage of cases in each county. That's missing from most every map you find.

Good point. I was thinking about that and will plan to add it in. You think something like cases per 100,000 would be a good metric?

Everyone uses either cases per 100000 or cases per million. Of course it's a messy number due to unequal access to testing, but eventually it will even out.
