Oh, one thing I’m not sure about is how to best map to an RGB space for the 3rd dimension. Presently I’m using swatch to convert a single value (via HSL) to an RGB array, but the problem with that is that 0 and 255 both equal red, so it wraps back around on itself. I initially tried scaling it so 0 = red and 255 = blue, but then the contents seemed really smooshed and not very differentiated. That could just be down to this particular dataset, but I imagine there’s a “standard” way to map via color for stuff like this.
