The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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.
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
100% of ZERO EMISSION TRANSPORTATION ASSOC’s revenue is contributions — more reliant on donations than three-quarters of its peers (88% for the typical peer).

53% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund ZERO EMISSION TRANSPORTATION ASSOC.
Largest funder’s share by year: 2021 46% · 2022 50% · 2023 40% — diversifying over time.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $2.0M arriving through sponsors registered in 2 statesis 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.
