The linkmap directive is supplied by the linkmap plugin.

This directive uses graphviz to generate a graph showing the links between a set of pages in the wiki. Example usage:

[[!linkmap  pages="* and !blog/* and !*/Discussion"]]

Only links between mapped pages will be shown; links pointing to or from unmapped pages will be omitted. If the pages to include are not specified, the links between all pages (and other files) in the wiki are mapped. For best results, only a small set of pages should be mapped, since otherwise the map can become very large, unweildy, and complicated. Also, the map is rebuilt whenever one of the mapped pages is changed, which can make the wiki a bit slow.

Here are descriptions of all the supported parameters to the linkmap directive:

• pages - A PageSpec of the pages to map.
• height, width - Limit the size of the map to a given height and width, in inches. Both must be specified for the limiting to take effect, otherwise the map's size is not limited.
