GraphArc (Macrofocus TreeMap API for Swing SpecificationA good and efficient starting point is the use of the SwingTreeMap component. It contains all the information to get started within minutes!To use this API, please make sure you have at least (this is the absolute minimum) the macrofocus-treemap-swing.jar, macrofocus-treemap.jar, macrofocus-common.jar, macrofocus-visualization.jar, and macrofocus-slider.jar libraries in your class path.)

java.lang.Object
- com.macrofocus.treemap.fastvoronoi.convexhull.GraphArc

```
public class GraphArc
extends java.lang.Object
```
The Conflict Graph is completely constructed of doubly-linked lists of GraphArcs stored in the facets and vertices of the convex hull. Each GraphArc indicates that the given facet and vertex are visible to each other and therefore in conflict.
