OK, this is the last visualization of Albertan Urban Population Density for a while. Again, inpired by this Gomitoli chart designed for Excel, I made this example using Albertan cities. The circle area roughly approximates the true city area, and there is a random point on the circle circumference drawn for every 1000 people in the city’s population. Smoothed PaperJS lines connects the points. Finally jQuery UI sliders and PaperJS buttons enable zoom and pan.
