A graph editor in Processing with some visual algorithms and physical movement (attraction/repulsion).

All the different releases can be found in the ./releases/<OS> folder.

1. Add a new node: right-click on an empty space.
2. Select/Deselect nodes: left-click on the desired node. A selected node is always circled red.
3. Connect nodes:

• select the first node
• left-click the second node

4. Delete a node:

• select the desired node
• hit the del key

5. Delete an edge: left-click on the edge nodes. Multi edges are not yet supported.
6. Show Eulerian path animation: hit the e key (if there is no Eulerian path, the screen will flash red). You can read more about the Eulerian path here.
7. Toggle physics: press the Physics button.

Note: Look out for the active node in order to prevent connecting something accidentally.
