A population density overlay would have been helpful as would a voting trend by state or even by municipality or district to understand if there are any statistically relevant discrepancies. That said, I suspect the point of this tool is to lower the barriers to voting to allow everyone's vote to be collected.
Almost, but my very densely populated state of Massachusetts has barely any trending searches for "provisional ballot", and none in Boston; whereas the swingier state of Ohio awash with trending "Provisional Ballot" searches.
Basically if it's a heavily populated area that is awake, then the dots are big.
Maybe as the day goes on it will level out to more interesting insights?
