The applet on this page is experimental software designed to demonstrate the principles of drawing Euler diagrams with circles. Start the demo. It requires the Java plugin version 6.0 or greater. If you use the results of this applet, we encourage you to reference the paper that describes how it works: G. Stapleton, J. Flower, P. Rodgers, J. Howse, Automatically Drawing Euler Diagrams with Circles, accepted by the Journal of Visual Languages and Computing 2012.
An earlier circles applet (which has some bugs).
