You assign a color based on two end points, e.g. red/blue with an intensity based on what your coordinates are

But that's just one dimension, red to blue. That works if you're measuring one thing. But how do you use this for two separate measures (i.e., two dimensions)?

Red on one dimension, blue on the other. You go white to pure red, and white to pure blue depending on where you are in the data's bounding box. So basically each country on a map gets a color based on

x * Red + y * blue

Something like that
