This interface defines IDataProvider keys for those layout algorithms that can handle hierarchically grouped graphs.
Remarks
There are two groups of IDataProvider keys. IDataProviders registered with NODE_ID_DP_KEY, GROUP_DP_KEY and PARENT_NODE_ID_DP_KEY define the relationship of nodes within the hierarchy. A parent node is defined for each node in the graph. This parent is the containing group node. For top-level nodes, this parent is null.
GROUP_NODE_INSETS_DP_KEY and MINIMUM_NODE_SIZE_DP_KEY are used for registering IDataProviders that add layout information to group nodes such as the insets and the minimum size respectively.
