It sounds like you have shapefiles (or some kind of geodata) that has roads and intersections. This is already a graph. You also say "with a non-geographic but schematic / ideal criterion" which somehow made me think of Graphviz, because it's designed to show non-geographic graphs and automatically lay them out. But now reading the above maybe all you want to do is symbolize your road / intersection network according to some attributes. If that's the case you don't need Graphviz I think, just some work on symbology driven by attribute values. Maybe you could give us a bit more detail, or maybe do a sketch with pen on paper and take a photo? -- Chris Hermansen · clhermansen "at" gmail "dot" com C'est ma façon de parler.
