What are ratings?

Ratings let you assess a visualisation according to:
 

Impact:
How much a visualisation makes you take notice of it
 

Accuracy:
How well it portrays the true data behind it
 

Rate visualisations according to your own impressions and expertise. We also ask you to let us know how you rate your own level of expertise in terms of data and visualisation, so that we can filter ratings further in future.
 

For more information on ratings and levels of expertise, see our help page.

Benefits & pitfalls to avoid
  • Using area or volume to represent data can distort data values, and exaggerate differences between values. For example, if the radius of the circle is used to represent data values, the area of the circle will quadruple if the data values double. There is also an issue of 'perceptual scaling' - the tendency of people to underestimate areas.
  • When using colours to portray data values or types, ensure that the colors used are accessible to all users. Online tools such as ColorBrewer (www.colorbrewer.org) can help identify issues with colours used.
Create your own
  • Bubble charts can be created in a range of standard data applications such as Excel.
  • Some combination charts, such as bar and line charts, can be created in standard applications such as Excel (using more than one axis). Others can be combined by saving visualisations as image files and combining in an image editor.
  • Comparative charts are used to compare things such as performance, ranks, changes or characteristics. Basic comparative charts can be created in standard applications such as Excel using line graphs.
