Edge routing using connection regions

摘要

A computer system identifies a source node that is to be connected to a target node, where the target node is connected to the source node using an edge that links a connection region associated with the source node to a candidate connection region of the target node. The computer system identifies candidate connection region constraints that place restrictions on where the candidate connection regions can be positioned on the target node and determines, based on the identified candidate connection region constraints, the position of each candidate connection region relative to the target node. At least two of the candidate connection regions are disconnected so that an edge's connection to the target node can change between the disconnected connection regions. The computer system also visually represents the position of each of the candidate connection regions of the target node.
