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.
