The homepage of Daily Radar [dailyradar.com], a seemingly very popular portal with male-oriented and US-centric content, features an interesting interactive stacked lined graph, visually similar to LastGraph, WaveGraph, MemeTracker, New York Times "Ebb and Flow of Movies and Tokyo: Right Now. Well, you know what I mean.
The graph shows the current trends over a spectrum of categories (e.g. music, technology, sports), and can be embedded in other websites, as you can see below. It is nice to see interactive graphs prominently featured on the very first page of large websites, in particular if they belong to the top visited of the web.
