That's so cool! It really feels like tech best practices have made lots of headway in the past 5 years within the U.S. government. Looks like this analytics frontend was brought to us by 18F, with the codebase even hosted on GitHub[0]. Other governments in the US also seem to be using this like the city of Los Angeles[1].
