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.

Benefits & pitfalls to avoid
  • Pie charts are often criticised. Comparing the size of pie segments can be difficult, and many visualisation experts suggest that bar-charts should be used instead.
  • Shaded maps can emphasise large areas much more than small ones - for example highlighting rural areas over urban, if fixed population areas such as Super Output Areas are shown. Consider providing an alternate mode in which values are represented by circles, or values are scaled by the area size (ie showing density).
