The attentive infosthetics might well remember the post at the beginning of this month about the online interactive map of biodiversity data from the Natural Science Museum of Barcelona. It seems its designers, the data visualization firm Bestiario, had originally planned even more, as today they launched a smoothly zoomable treemap, titled Biodiversity Tree [], showing the same dataset. Navigation occurs through clicking unto, or outside of, the individual rectangles, or using the schematic diagram below.

Zoomable treemaps are not a particularly new idea, as one can observe the Treemap or the (now defunct) Browse Goods interface, but no implementation has accomplished similarly smooth zooming animations.

Could it these biodiversity data interfaces are still missing some intuitive way for lay people to even get interested in this topic?
