There's something about it that worries me a bit, though: charts don't have scales. Removing scales from graphics seems to be getting more popular lately among data journalists, and it works in some cases here: some of these charts have horizontal reference lines—see animation on the right—that help you get a sense of proportion and variation.
But the following set of line charts lacks any reference and, moreover, it seems that each one is based on a different scale: New York has more daily confirmed cases than Florida—thousands versus hundreds—but the last point on Florida's line is higher than New York's. New Hampshire has a 7-day average of around 100 cases; Maine has a bit more than 20. I understand that the goal of these graphics is to reveal upward and downward trends, not the case count itself, but I fear that this design choice may mislead some readers:
Here are those charts with scales:
What could be an alternative here, I wonder? It's tricky. There might not be an ideal solution, as it often happens in visualization; adding detailed labels would clutter these tiny charts. Perhaps not to show daily new confirmed cases, but some sort of index—percentage change based on a common starting point for all states,—or the variation in comparison to the previous day or week?
