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.

    That's a very cool plugin. – Radar Jun 20 '13 at 20:08

    Flowmapper desperately needs a new interface. For instance, why is it taking text files from the system as an input? Why not use centroid shapefiles in the browser. – gregmacfarlane Feb 28 '18 at 19:37
