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.

Parallel Sets (ParSets)
Parallel Sets is a technique for visualizing categorical data. It helps you get away from representing individual data points, and instead show sets and subsets of items with certain combinations of criteria.
This example illustrates the people on board the Titanic. In a way, ParSets is a mix between parallel coordinates and treemaps/mosaic plots.

  • 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.
  • Parallel coordinates (profile graphs) are comparative charts comparing several characteristics at a given point in time. Parallel coordinatescan be created in a range of standard data applications such as Excel PeltierTech has a post on how to create these in Excel.
  • A Treemap is a visualisation of hierarchical structure. You can upload data to online tools such as Many Eyes to create interactive Treemaps. However, we are not aware of any standard desktop tools that can be used to create Treemaps (please email if you know of anything!).
