Visualizing OD-Matrix

[xintan]

Hi,

Any idea how to draw straight lines From Origin to several Destinations according to a OD-Matrix?

Since I have the coordinates of the center of each zone, So the problem is How Can I access the attribute table of the map layer and How to import the OD-matrix.

I just want to do the same thing as the following map in Flex.
