Scatter (xy plot) graph

this is what I have [color=#333333][/color] , (press Visa to see the animation) not Flash but it works and is built by 200 manual made animations!!!. Now I would very much like to improve this so a visitor could choose a company from the combobox and immeadetly the corresponding point starts moving, glowing etc. Does anybody know a good point to start searching for a newbe?
