Junk Viz Examples

I have obtained all three examples from Paul Kedrosky's blog, Infectious Greed.

  A fake 3D bar chart. And a gradient effect. Two egregious errors in one chart.

  An otherwise useful chart that is marred by the use of distracting gridlines, that overpower the data plotted. The obtrusive gridlines are non-data pixels.

  Fake 3D charts, i.e., charts that plot data in two dimensions only, but have the artifact of a three-dimensional effect added, make it difficult to understand the data plotted. The line chart above is one such example.
