The emissions graph only considers particulates, so it's massively undercounting air pollution improvements from EVs.

Do you have figures for this? it says: "non-exhaust par­ti­cles represent 59% of PM10 and 45% of PM2.5 emis­sions", so about half of fine particles are non-exhaust (brake, tires, road dust). If you also count the fabrication process, the batteries, the new infrastructures and electricity footprint, the additional weight (for the same size), it's possibly a small gain over thermic engines, but nothing super obvious
