Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.

Funder states come from each funder’s own filing. $26k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been.
