Haha, fair.

But in my defence, i had limited real estate to work with. In a Tumblr note, i explain that it was meant simultaneously as an overlay for a playable phone keyboard app that i have.

Just follow the colors, it's the most important thing. Also capital letters, things' initials, underlines, and sides of hexagons on which things are, all matter. And there are two colored bullets, violet and orange, which are 'secondary' reference points for some things, even though those things belong, topically, to areas elsewhere in the chart.

Also pay attention to whether things are on 'depressed' or 'elevated' areas (minor and major) areas, via the shadow. Eg. many transparent, minor, ununderlined, things fall on 'depressed'.

Also, i'll grant you that i put in an easter egg or two (not affecting the chart's meaning, only some of its form). Eg. hexadecimal digits. But they're an exception.

Edit: it's really rather meant to be, if anything, a companion to reading a textbook or something, the way i learned as i was making it over a couple of weeks.
