Applet/Flash program Of 2D range tree datastructure

I need a visual representation of 2-D range tree. It should basically take user specified number of points (say n). It should first take n as the input and then take n points (x, y) co-ordinates as the input. It should then show the creation (animated) of the 2-D range tree, i.e. first a balanced binary tree on the x co-ordinates and then each of the nodes should contain a balanced tree on the y co-ordinates. Then after the creation it should handle queries in the form of a query rectangle (x1, y1) {left bottom}, (x2,y2) {right top} should be taken as the input, as the output all the points lying in the query rectangle should be highlighted and displayed. about range trees: [login to view URL]~sellares/ComGeo/[login to view URL] about data structure viz: [login to view URL]~galles/visualization/[login to view URL] {just as an example}
