> PrivGraph - Display and manipulate directed graphsI developed this code for a serious application, but it can also be a lot of fun to play with.This view implements an automatic layout of directed graphs using a force-directed placement algorithm. The algorithm is fast enough to give real-time layout for up to a few hundred nodes on a CPU with hardware floating-point support. Layout is performed in a 3 dimensional volume; optionally, this may be constrained to a 2 dimensional plane. The display volume can be rotated, nodes can be moved, and new nodes and edges can be added using the mouse.This view demonstrates a few interesting features of the Blackbox framework.    * Double-buffered display to avoid flicker during animation.    * Non-destructive drawing during mouse tracking.    * Control of view properties using Properties.SetMsg/PollMsg and the framework functions Properties.EmitProp/CollectProp. It may also be a useful example for someone interested in displaying or manipulating 3D data. See Priv/Docu/Graph for details.
