Trendmap on DailyRadar

DailyRadar uses a stream graph to display trends over the past few hours. The small applet lets the user choose between different topics ranging from Technology to Entertainement.

The size of the applet and the used color scheme diminish the usefulness but it gives a quick overview at the first glance. What I would love to see DailyRadar doing is opening up this small application and let the user customize the input. This could be an intersting method to measure, track and compare trends (in a similar way trends.google.com works)

trendmap_011The visualization method reminded me of the LastGraph project, which I highly recommend if you haven’t come across it yet. LastGraph uses data from last.fm and creates a stream graph visualization of the listening history.

  • Isn't that just a stacked area graph (http://interface.fh-potsdam.de/infodesignpatter...) with Bézier curves? Makes no sense because it suggests there was some kind of flow in between… Nice color choice though.
  • @Paul: You're completely right with the stacked area chart. The difference from a typical stacked area chart is the "floating" off the ground. Lee Byron, who wrote a paper about this visualization method describes the visualization method as follows:

    The layout method is unique, dubbed a “Stream Graph,” it acts to have the least amount of distortion to the graph and is responsible for generating the elegant non-symmetrical curves.


    I hope this clearifies my misinterpretation and thanks again for the advice.
