Meta Data Provider: layouter.GraphvizMetaDataProvider
Description
Radial layouts, after Wills ‘97. The nodes are placed on concentric circles depending on their distance from a given root node. The algorithm is designed to handle not only small graphs, but also very large ones.
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.
