These have been done. There is already a Heap that is used in the 
Morphic scheduler.

Diego Gomez Deck has done a PlotMorph (on SqueakMap).

There are some graph libraries on SqueakMap for the algorithm part of 
the question.

Use Morphic for display.

Use Connectors (from SqueakMap) for displaying your graphs. Soon I 
will post version 2 of Connectors, which has a number of 
improvements.

The attached images are from my new work.
