[Editor's note: Uses the Flare visualization API in Flash ActionScript 3 to display data about the Post 200 companies in a treemap format. A vexing and il-documented API, but powerful. We considered showing the data with a graduated circle map but the company locations were too clustered for that to be effective.]
