Generate Venn diagrams with this software. VennGenerator help you create Venn diagrams. You can specify the area, axis ratio, angle, and color for each oval, and then drag the ovals into position to get the desired amount of overlap. To help you achieve accurate intersections, the program reports the areas of all component regions in a list. These have slight variations due to rounding, but are still much more precise than just placing the ovals by eye.
