I jumped over from Raphael back to Processing again today. I have said it before: us Flash guys might get frustrated trying to pull off some simple stuff in either Processing or Raphael. Just keep in mind that they are young languages and the future looks bright.
Anyway, another attempt to do something here with Processing. It took a me minute to find an elegant way to get Twitter JSON data into Processing without being too sloppy. The visualizer works perfectly in Safari and Chrome, but it’s completely hosed in Firefox.
