A concept map sample depicting various suggested relationships between different ideas. See also the Interactive Force sample that uses the exact same data but a different node template and an interactive ForceDirectedLayout.
This predefined layout treats the graph as if it were a system of physical bodies with forces acting on and between them. The layout iteratively moves nodes and links to minimize the total sum of forces on each node. The resulting layout will normally not contain overlapping Nodes, excluding cases where the graph is densely interconnected. More information can be found in the GoJS Intro.
