2. Graphical Representation
Display elements and their relationships visually for non computer scientists.

3. JGraph for Visualizing Networks
JGraph is an open source graph visualization library written in Java.
JGraph is a fully Swing compatible component.
Simplifies drawing process for networks, trees, and maps.
Fairly versatile: Vertices and edges may be shapes, images, other Swing components, or animations.

5. Algorithm for Drawing Small Explanation Networks
Determine what element to display
heuristic to estimate what elements should be placed next
number of links
number of sub/super elements
relation to already placed elements
Determine where to place element
estimate text size
estimate approximate space needed
minimize cross-links
