Show HN: SMA and Per100k-normalized graphs of Covid-19 cases/deaths by country

Since daily COVID-19 figures in seem to vary wildly (owing to fewer cases counted at weekends, excessive cases counted after weekends, and ongoing corrections/adjustments), I built a tool to graph simple moving averages (e.g. 7-day-SMA, 30-day-SMA) of COVID-19 cases and deaths. This smooths things out and gives a clearer picture of general trends. The tool also allows you to normalize the same data per 100k people (to allow better immediate comparison between countries).

It uses the Johns Hopkins university data and updates automatically with the latest daily figures. I've got it running on an iPad in the corner of the room where it casts a warm, if somewhat miserable, glow on the room in the evenings.

Comments and feature suggestions welcome! Two features I already plan to add are:

- implementing swipe left/right to flip through countries - data for a couple of notable countries is missing - I will of course add them (I need to aggregate the data for those first, as John Hopkins are publishing the figures broken down by region for those)
