Abstract
Techniques are provided for preserving angles at graph elbows as graph nodes are moved. A graph, which includes a first segment and a second segment that form an acute or obtuse angle at a vertex, is displayed. The first segment has a first end opposite the vertex at a first position; the second segment has a second end opposite the vertex at a second position. User input moves the second end from the second position to a third position. In response, the angle is automatically preserved by modifying a length of the first segment and a length of the second segment, without modifying the first position of the first end. Other techniques can replace two segments with a single segment if one of the segments becomes too short, or snap an elbow angle to a specified angle if moving the node causes the elbow angle to near the specified angle.
