This (https://ncov2019.live/map) started as the best, most (practically, conveniently) informative and updated "dashboard" I've found. It was posted to HN several times (where I discovered it), but underwent some curious changes over the last few days. Initially, it showed all known events and included links for additional information. Then, peculiarly, all the cases in Florida disappeared with no trace, and now the southern US seems to have been scrubbed of accounts.

It was produced mostly by a highschool student in WA.
