Agreed for the most part, although there are rare valid uses for 3d graphs. I think most contemporary data vis people would say that Excel makes it possible to make pie charts at all means it may encourage bad practices.
I can think of one-- we had a 96-element datatable (12x8) and limited space in our biochemical journal article. We were looking to graphically show differences in orders of magnitude to help explain the assay. A 3d column chart fit the bill because we could show lots of data in a small space, and readers could quickly see the range of values.
