How can I show the flow coming from an Origin-Destination matrix as desire lines?

I need a result like the one in the picture below.

desire lines

I need to scale them proportionally to its value (coming from a linked MDB) and I like that the lines are a bit curved (but I can use straight lines too).

Try using the QGIS plugin Flowmapper. The attached image is a sample from the plugin documentation.
