if anyone knows of a yarn interval type visualization like this

excluding mamplayer, please say so.

It’s not really on the topic of MIDI, but there is a cool “circle” interface in the OP-1 that reminded me of the picture you posted. Fast forward to 1:10 in the video. Cool visualizations for their other modes too.
