ELK Mr. Tree
| Property | Value |
|---|---|
| Identifier: | org.eclipse.elk.mrtree |
| Meta Data Provider: | options.MrTreeMetaDataProvider |
Description
Tree-based algorithm provided by the Eclipse Layout Kernel. Computes a spanning tree of the input graph and arranges all nodes according to the resulting parent-children hierarchy. I pity the fool who doesn’t use Mr. Tree Layout.
Category: Tree
Specialized layout methods for trees, i.e. acyclic graphs. The regular structure of graphs that have no undirected cycles can be emphasized using an algorithm of this type.
