One problem with many of these dot representations is that the dots occlude other dots. This is particularly a problem when zoomed out. This visually overrepresents the dots drawn last. For example, look at a blown up version of this area: http://i.imgur.com/XA9IDqy.png http://i.imgur.com/XA9IDqy.png Blue and red might be equal in numbers in this area, but because blue occludes red, unless you zoom in, all you see is a predominately blue region. A quick solution is to put all dots in a list, shuffle the list, then draw each dot -- instead of drawing all of one color at a time.
