Chartjunk is what happens when your data design focuses too much on the design aspect.

As the example above demonstrates, the chart does not need the addition of perspective. If anything, it makes it harder to interpret the data.

Distracting patterns, overbearing colors and even unnecessary grids and outlines are just some of the elements of chartjunk.

“Chartjunk can turn bores into disasters, but it can never rescue a thin data set.” - Edward Tufte
