Compact Tabular Layout

This demo shows how to configure the TabularLayout to create compact drawings.

The algorithm tries to calculate an arrangement that minimizes edge lengths. Since tabular layout only supports straight-line edges, EdgeRouter is used to calculate the final edge paths.

If the Preserve Aspect Ratio button in the toolbar is selected, the tabular layout algorithm will use layout policy FIXED_SIZE to arrange the graph with an aspect ratio close to the aspect ratio of the GraphComponent. Otherwise, the algorithm will use layout policy AUTO_SIZE to get a result that is as compact as possible.

If layout policy FIXED_SIZE is used, the tabular layout algorithm requires a PartitionGrid that defines the columns and rows for the resulting tabular arrangement. A PartitionGrid is not necessary for layout policy AUTO_SIZE. However, an empty grid may be given to the algorithm to specify the distances between the automatically calculated columns and rows.
