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
  • 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).
Create your own
  • Chloropleth maps can be created in a range of desktop GIS applications such as MapInfo and ArcGIS.
  • 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.
