The use of the typically green/red colored treemaps to depict the stock market exchange is not particularly new, especially for those who know the now famous SmartMoney Map of the Market. However, FinViz.com takes the more traditional flat treemap version one step further by introducing a 2.5-dimensional perspective [finviz.com] as well as a geographical overview [finviz.com] version.

The height of the fake 3D blocks depicts the relative change in stock market price. The world map version gives a somewhat quick glance of the actual global financial state.




Seems to me that the ability to communicate information here is poor. That "2.5-dimensional perspective" comes across (to me) as a useless, incoherent jumble.

I was afraid someone would say so. :)...

Obviously, a real 3D videogame-like landscape visible through stereoscopic goggles would be more fun (but probably also useless).

Seriously, I believe simple color-coding (instead of "height") is good enough for this sort of complex grids. Just like we have in biology, with microarrays. The goal is to quickly make people understand what the big picture is : for example, lots of red in "finance stocks", or lots of green in "Oil stocks".

I like their Google-Maps like navigation and zoom through stocks landscapes, though. Very fast and smooth transition from the big picture to the small detail.
