record a video of you jamming on it and explaining it. there's nothing intuitive here.
Looked around to see what could be least clear.
Marked that the faint pink boundary in the center is the minor scale / aeolian mode (i believe), as opposed to the main thick boundary, of the ionian mode.
Changed the violet vertical bars along the right edge of G4 and left edge of F4, standing for that excepting for the locrian and lydian modes, all modes contain the main P5 and P4 intervals. Fair, they may have suggested an absence, evoking a dash. Replaced them with ~~five~~ six (filled) bullets, representing the ~~five~~ six modes.
(I may yet change the execution of those.)
As for the large blue boundary, it is just to help me visualize that all simple intervals form a quadrangle.
its possible that this is a brilliant breakthrough somehow, but it looks to me like a chemist is trying to invent a musical periodic table.
walk us through it, how would we play it?
I see this comment has been upvoted.
Really, it is just a keyboard with an extra dimension. (The 'circle of sevenths' follows, on the chart diagonally through the whole, the pattern of b&w keys on a standard keyboard; i marked it with the small raised b&w bullets.)
The keyboard app i made it for -- the newest fork / release of it, at least -- supports chords, as well as playing triads with a single tap, if you tap a vertex within a configurable distance.
The rest is just, well, knowing the stuff you want to play. (I made the chart so that it helps me with this part.) The intervals and degrees are marked.
Here are the links to the libre apps' binaries:

https://apkpure.com/designoverlay/com.ms_square.android.design.overlay/download (Github page has no releases; can't vouch for this site, disabled internet permission for this download myself)
Edit: i suppose my point is, it is literally not any harder than the regular keyboard to play. Because the 'circle of sevenths' and 'the circle of seconds' ~~literally~~ are the standard keyboard in the first place.
Even if my markings were all confusing, which would be fair to say, they would still at most result in a standard keyboard with, well, an added piece of graffiti on top of it. You can just ignore them.
Left/right is semitones, up/down is fifths.
Edit: i got confused there for a second. My words weren't wrong, as such, and the chart is correct; the diagonal line indeed represents the standard keyboard layout. But for a moment, here in the thread, i thought / replied as if it were a direct one, eg. in steps of semitones. Of course it is not so; that line is in steps of sevenths, which i briefly forgot of.
But still, my point stands that the underlying keyboard is very simple. It just goes left to right, then wraps around bottom to top, intuitively. On the very bottom and the very top of it, you can see black boundaries of the standard 88 key piano range.
