Linear Diagram Generator

To use this tool, enter the sets that intersect on each line, separated by spaces. The diagram will not change until the "Redraw Diagram" button is pressed.

This is a diagram that shows the intersections of a number of sets. It can be used as an alternative to a Venn or Euler diagram. There is evidence that linear diagrams are more easily interpreted than the other kinds of diagram^1,2.
Some help on how to interpret linear diagrams.

Length Proportional Diagrams

It is possible to use this tool to generate length proportional diagrams, where the widths of the intersections are proportional to input values. To use this facility, add a space followed by the required value to every intersection. An example of a length proportional diagram.
