Emerging topics update

My thesis is due pretty soon, so I am currently writing A LOT and make some on–the–go beautifications to my experiments.

First one is the emerging topics histogram. I followed my own advice and vertically centered the stacked histogram. Additionally, I never liked those sharp edges, so now I do not only “fade out” tags visually, but also fade them in, resulting in a much more organic picture, and largely improved readability of the chart. New color scheme: old tags are cold, freshly introduced ones in warm color. This is all very much inspired by the fabulous last.fm charts by Lee Byron — thanks!

    One thing I forgot: Credit where credit is due; this type of visualization has been around for quite a while already: http://infoviz.pnl.gov/pdf/themeriver99.pdf

    It’s amazing ! Is there a way to have it in a free/open source licence ?

    This is great for correlating a tag’s popularity with a surge in use of the service, as I think you already noted. Maybe to add an additional dimension of data, you could base a tag’s decay upon how useful it is (i.e. how many times people access bookmarks with that tag). It would be a different way of looking at the data; “useful” tags will stick around longer, and you will weed out tags that nobody finds useful.
