Hello, I want to render a roadmap, with intersecting roads, ideally of varying colours and widths. If you look at this link http://multimap.com/map/browse.cgi?client=public&X=450250.335217983&Y=197750.157094552&width=500&height=300&gride=&gridn=&srec=0&coordsys=gb&db=freegaz&addr1=&addr2=&addr3=&pc=&advanced=&local=&localinfosel=&kw=&inmap=&table=&ovtype=&zm=0&scale=5000&right.x=7&right.y=99 you'll get a pretty good likeness of what I'm aiming for. If I start off with a data structure of line segments connected I want to be able to use this to generate the stuff. Any ideas?

Oops, I thought that link would wrap. Sorry!
