Library to create Schematic maps (ie; Tube, metro maps) in flash

Are you looking for helpful drawing libraries? Data Visualization libraries?

this site/blog is great and he's got a few classes (CubicBezier..) http://www.cartogrammar.com/blog

Farmcode.org has a open-source library that is great for tons of reasons, and they've made a 'fast 2D bezier' class.

Grant Skinner and Quasimondo have both released invaluable open-source stuff.

hope these help!
