Why does the chromaticity diagram look like that?

I think a good explanation of color spaces might be starting at a camera sensor with a bayer array and how that’s processed.

Starting with the function of the human eye seems like a good choice, I mean how else would you explain why a Bayer matrix only has 3 colours?

I was imagining a more simultaneous exploration of bayer matrices, human eyes, and color. For example, that question of why 3 colors, or why 2 green pixels, opens the door effectively to a lot of ideas.
