Venn Diagram Plotter

This program will draw correctly proportioned and positioned Venn Diagrams, supporting both 2-Circle and 3-circle Venn diagrams (though the overlap regions of 3-circle Venn diagrams are not always to scale). A Venn diagram is a method of visualizing the amount of overlap Between two (or three) lists of data, using circles to signify the size of each circle and positioning the circles such that the area of overlap represents the amount of list overlap.
