What is a pie chart?

A pie chart (or circle chart) is a circular graphic whose total area represents 100%. It is used to visualize the proportions of different parts of a whole.

In a pie chart, each slice is proportional to the value it represents (this proportional relation is evident in many ways: through the slice’s angle, total area, as well as its arc length). The pie chart is widely used in newsrooms, business, and educational contexts to present the composition of demographic data, statistical numbers, market shares, etc., at a glance.

Best uses for the pie chart
  • Showing the composition of demographic data, like the size of your market share in different geolocations
  • Highlighting ‘stand out’ percentages, particularly in news, business or academic reports, and communicative information
  • SEO website traffic analysis - where are your biggest sources of traffic online?

Pie chart: pro tips
  • As a pie chart is a proportional representation, it only works for values that add to 100% (otherwise, try a bar chart)
  • If your chart has many sections that make it difficult to read, try grouping all data below the top 5 categories into one section titled ‘Other’
  • If the labels for your sections are still overlapping even after re-grouping as above, try changing the “Layout settings” on the “APPEARANCE” tab (the check box “Labels as list” is particularly helpful)
  • Always sort your chart sections by value: the largest share should be placed at 12o’clock, with the rest of the shares positioned clockwise in descending order (excluding the ‘Other’ section, which must always come last)
  • For the design, sticking to gradients of one color and using a contrasting color to emphasise key data will make your chart easy to interpret–especially if you fade the ‘Other’ section to a pale grey to show that the other sections have greater significance
  • 3D pies tend to distort our understanding of the proportions of shares (the depth of the chart creates the illusion of extra volume in some slices and not others)–so stick to 2D if you want to communicate accurately
