Hi HN, this is a little pet project we created over the last couple of weeks. We created "Software EKG" a while back as an internal tool to analyze large amounts of time series data collected on production systems. This was before things like Prometheus and Grafana existed and it proved to be a valuable tool in our belt when we had to hunt down performance issues and relate different metrics like harddisk I/O and request latency in our application.

This depends in the broadest sense on what data you want to have and which data source you trust. The OWID data is a good data source for our use case because it collects many data characteristics from all over the world and is very trustworthy at the same time. On the other hand, you can't break down this data further than on a country level.
Other data sources differentiate more in terms of geographical characteristics, but include a smaller amount of other information, e.g. the New York Times data used by Google (https://www.google.com/search?q=covid+data+usa+county+state).
