This chart is nice, but you need to include the difficulty of the algorithm (difficulty to attack), the size of the blockchain (hard for anyone except rich people to participate if you need a server farm just to verify a transaction), developer activity, and each coin should have a collapsable subset of “layer-2” options (eg. Lightning and liquid for Bitcoin), and their statistics as well.

Most importantly, A “transaction” on a blockchain is not a “transaction” in the colloquial sense.
