Show HN: Covid-19 USA states and counties Time series data website

My friend and I wanted to contribute and help everyone to better understand the outbreak solely in the US so we built a website that tracks US covid-19 cases on a state/county level (where the data is available) and present their temporal evolution (time series). I was in charge of the front-end while my friend did data aggregation and manipulation. We are aware that there are already a lot of trackers out there but this one is US specific and tracks the cases in greater spatial and temporal detail, while still keeping it clean and simple (or so we hope). NY times seems to be way ahead of the curve in reporting and data visualization of covid-19 cases around the world but as far as I know (unless it changed) they are behind a paywall after a certain amount of website visits.

This just went live after a few days of almost not-stop work. It can certainly be improved and we would like to hear back from you with all of your suggestions and criticism. We wanted to make it public as soon as possible so we can start iterating and improving.

I know that the map is a little bit sluggish, this is probably because I am loading a ton of polygons which define the borders of every single county. I need a little break from this but I will try to improve it when I get a chance.

The data is collected by NY Times and is freely available for public use (attribution at the bottom of our website).

Our ToDo list: Plot the rate of change of cases per each location available Produce a heatmap which shows the amount of infected/per population number
