INTERACTIVE CONTROL OF THE CURVATURE OF LINKS

摘要

A link curvature processing module enables a user with the ability to control the curvature of links in a node-link diagram. As a node-link diagram is displayed to a user, the user may interact with the diagram and adjust the curvature of one or more links in the diagram to improve the readability of the diagram. The user's modification to the curvature of a link alters the shape of the link so that the position of the nodes connected to the link does not change. By providing the user with such control, the user is able to tailor the visual display of the links to the user's preference.

1. A computer-implemented method, comprising:
displaying a node-link diagram in a first visual layout, the node-link diagram having a plurality of nodes and a plurality of links, each link being a curve that connects a source node and a target node; detecting a user action to the displayed node-link diagram that indicates modification to a curvature of one or more links associated with a subset of links, the user action fanning out the links to a fanning radius; and generating a second visual layout, the second visual layout displaying each link in the subset with a modified curvature of each link that differs from the first visual layout, the second visual layout altering a curvature of each link based on the fanning radius without changing a position of a source node and a target node connected to each link in the subset.
