Draw API

Changes

Added a new API for drawing nodes and edges on an existing graph and animating the transition into a new graph layout.

Try the proof-of-concept D3 Graphviz GUI Editor made with it.

The new methods are:

• drawEdge
• updateDrawnEdge
• moveDrawnEdgeEndPoint
• insertDrawnEdge
• removeDrawnEdge
• drawNode
• updateDrawnNode
• insertDrawnNode
• removeDrawnNode

Fixes

• Corrected pan and zoom not working after the graph ID had been changed
