Venn diagrams allow to refine our view of the scores to measure tool complementarity. Each answer provided by a tool is a data point, we draw one circle per tool to contain all these points, and measure the overlaps with other selected tools. You can filter the data as desired and choose the tools to compare, and the Draw button will compute the diagram on the fly, which may take a few seconds.
Double click the numbers on the diagram to have a list of points. Refer to the "Index" column of the resolution table to understand the list of integers. You can also download this table as CSV.
