    "Topographical" data representation

    Kobe Royo

      Is there any way to display data in a similar fashion the image below? (data is present via topo)

          Hi Kobe,


          There are not any 3-D effects in Tableau. However, by using color or size, the same information could be displayed.

            Kobe, his 'alternative view' is much more informative:



            But they both suffer from the same 'perception' issue. For instance in the one labeled 'Vehicle Theft' which peak is 2nd highest, and which is 5th? Oh and what's going happening on the backside of those slopes -- gradual fall-off or sharp decline? (Both views suffer from this problem.) The whole reason to visualize data is to gain some insight, but those insights can be greatly skewed when you add the pseudo-third dimension.


            Tableau was founded/created by a few data visualization scientist out of Stanford. I seriously doubt they will ever allow a third dimension into Tableau.


            But interesting to know Chinatown seems to be the epicenter for most crime in SF; when I'm there for the America's Cup I'll keep that in mind.

              And to Tracy's point, look at the commentary:



              But such divergent POVs.
