INCREMENTAL AUTOMATIC LAYOUT OF GRAPH DIAGRAM

摘要

Adding new nodes to a graph diagram. A set of one or more new nodes is identified from a graph to be added to an existing graph diagram. A set of one or more anchor candidate nodes are identified in the graph that are coupled to the nodes in the set of one or more new nodes. One of the nodes in the set of one or more anchor candidate nodes is selected as an anchor node. An automatic graph diagram layout of the anchor node and new nodes that are to be coupled to the anchor node is performed to create a disjoint graph diagram. A spatial offset from the anchor node to each of the new nodes coupled to the anchor node in the disjoint graph diagram is identified. Each of the new nodes is added to the existing graph diagram while maintaining the identified spatial offsets.
