That's simply a 3D graph, why is that so hard to understand?
pseudo 3d on a 2d screen is the worst invention ever. the chart should be a (sort of) 2d matrix, where the height of the bars is indicated by a color coding. color-bar on the side as a legend tells you the amounts, that's all.edit: along this: http://matplotlib.org/examples/pylab_examples/tricontour_demo.html
I believe it would not be so useful as the human eye has issues with color. It is typically only useful for certain things. Feel free to prove me wrong or I may give it a try myself sometime.
