Please draw any planar graph by drawing the vertices on the applet
below. Edges will automatically be completed for you. Then click on the button below (scroll down) to get the dual of your planar graph. Note:
Please draw your graph in the center because
if your graph is over-sized, the dual representation may go off the width and height sizes I defined in this html file. For the best effect,
start with
three vertices and add
vertices only in the interior faces.
I modified the source codes from Lincon's Homepage and the other links off the class homepage.
I got rid of some bugs in List.java too. Source codes are shown below:
