A quick update for anyone using or interested in DiggGraphr Desktop. I ported the application to AIR today (it was a fairly painless operation requiring changes to just the application descriptor XML file and the parent tag of the application). So go ahead and get the latest build from here. For the uninitiated, the DiggGraphr Desktop application uses the treemap algorithm (with the theme from the newsmap application by marumushi) to render out Digg stories in treemaps. Customization even include auto refresh and custom pages. Details can be found on the application page here.
