Choosing the right graph

“If the statistics are boring, then you’ve got the wrong numbers.” 
― Edward Tufte (pioneer of data visualization )

Bar-charts and pie-charts tend to be the most used charts, personally I am a fan of Venn diagrams.

I wish I had this graph when I was at school.

Another favourite:

Choosing the right graph to present data can be difficult. We tend to use pie-charts because they look visually interesting in PowerPoint presentations, but pie-charts are usually the wrong choice, as they:

  1. force us to compare areas (or angles), which can be difficult,
  2. people tend to only compare the biggest two or three wedges and
  3. they take up a lot of space to be readable.
