GE has put together an interactive toy for looking at how expensive different illnesses are at different ages. Use the slider at the bottom to pick the age. “Wedges are colored by chronic condition and wedge size (angle), represents the percentage of patients with the condition. Wedge length from center to edge is cost. The lightly colored portions are personal cost and the darkly colored are insurer cost.”  (via FlowingData) Robert Kosara has a detailed critique of the chart over at eagereyes.
