The data endpoint is consistently taking ~30-60 seconds to resolve, and returns a 503 code when it does, with the heroku application error page as content: https://www.herokucdn.com/error-pages/application-error.html

Given the timeout before error, I suspect it's an error somewhere in the buildData() function, which causes data = await buildData() to equal a never-resolving promise, which causes app.get('/api/data', (req, res) => res.json(data)) to hang.

I can't be sure as I can't see the logs, but I'd be more than happy to open a PR if you can make the logs available!

Hey, awesome visualization!

Out of curiosity, are you happy doing daily manual updates or would you like to move toward automating them? This could probably be done with heroku scheduler, github actions (assuming that you have heroku deploy on github push), or by modifying the server to fetch and store the assets on the local filesystem (and then update the data directory on a schedule via something like node-cron).

When looking at population %ages, I noticed that New York City seemed very high around 4/17. It seems that the population is being sourced from Manhattan (36061) while the case count from CSSEGISandData represents all 5 boroughs (CSSEGISandData/COVID-19#1970). I believe USAFacts has breakout data, or the population JSON could just be modified.
