In the days of PowerPoint 2003 and older versions, you just had to insert a chart to end up with a 3D chart! Yes, that's true - and to say that this chart looks horrible is an understatement. Comparatively, the default column chart you add in newer versions of PowerPoint is so much more cleaner. Of course, changing the defaults does not mean that you will not encounter any 3D charts since even in newer versions.
