Attribute Descriptions

+
Damping +
Factor damping force motions. On each iteration, a nodes movement + is limited to this factor of its potential motion. By being less than + 1.0, the system tends to ``cool'', thereby preventing cycling. + +
K +
Spring constant used in virtual physical model. It roughly corresponds + to an ideal edge length (in inches), in that increasing K tends to + increase the distance between nodes. + Note that the edge attribute len can be used to + override this value for adjacent nodes. + +
URL +
Hyperlinks incorporated into device-dependent output. + At present, used in ps2, cmap, i*map and svg formats. + For all these formats, URLs can be attached to nodes, edges and + clusters. URL attributes can also be attached to the root graph in ps2, + cmap and i*map formats. This serves as the base URL for relative URLs in the + former, and as the default image map file in the latter. +

+ For svg, cmapx and imap output, the active area for a node is its + visible image. + For example, an unfilled + node with no drawn boundary will only be active on its label. + For other output, the active area is its bounding box. + The active area for a cluster is its bounding box. + For edges, the active areas are small circles where the edge contacts its head + and tail nodes. In addition, for svg, cmapx and imap, the active area + includes a thin polygon approximating the edge. The circles may + overlap the related node, and the edge URL dominates. + If the edge has a label, this will also be active. + Finally, if the edge has a head or tail label, this will also be active. +

+ Note that, for edges, the attributes headURL, + tailURL, labelURL and + edgeURL allow control of various parts of an + edge. + Also note that, if active areas of two edges overlap, it is unspecified + which area dominates. +
