this diagram is very cool. top left all looks like same color to me

Same. What do the X and Y axes mean here? How does the X Y coords relate to RGB?

The wave length from 470 -580 seems to take more than half of the space. Why don't we make a linear region?

CIE 1931 model defines Y as the luminance, Z as the blue in CIE RGB, and X as the mix of three CIE RGB curves chosen so that all values in the xy chromaticity space are positive.
The x and y axis in the diagram correspond to normalized values where:
x = X / (X + Y + Z) and y = Y / (X + Y + Z).

It's interesting to see how the axes of the ellipses are aligned.

Are there 3d representations somewhere?

Are there any trends of how different people perceive just noticeable differences?

When was the last time color acuity was measured?
