Does MapPoint, or any of its add-ons, have the capability to display flow from one point to another? I am looking for lines between points whose width is proportional to amount of flow.

Example, I would like to import 10 locations and the amount of traffic that flowed between all possible pairs of those 10 locations. I would like to see a network diagram with straight lines between all the pairs with their width scaled to the amount of flow.

I have seen these maps drawn before, but dont know what software is able to do it.

If not MapPoint, what other mapping software could do this?
