Venn Diagrams

Venn Diagram

A VennClosed The name comes from John Venn, a 19th-century British logician who devised the notion. diagram gives a colourful, graphical representation of how data interrelates. It is advantageous in segmenting the data, for example, when creating target groups for mailings. You can use the Venn to select and analyse your chosen dataset, and then filter a dashboard.

Click on a subset count to zoom in and see a tooltip with details.

Up to five sets can be used in a Venn diagram. A coloured ellipse representing each set is shown in a different colour. Five default colours are used, however, you can change the colour for each set.
