I've been working on a visualization project for 2-dimensional continuous data. It's the kind of thing you could use to study elevation data or temperature patterns on a 2D map. At its core, it's really a way of flattening 3-dimensions into two-dimensions-plus-color. In my particular field of study, I'm not actually working with geographical elevation data, but it's a good metaphor, so I'll stick with it throughout this post. Anyhow, at this point, I have a "continuous color" renderer that I'm very pleased with: The gradient is the standard color-wheel, where red pixels indicate coordinates
