It would be cool to have SVG graphics that show on wiki pages and can contain links to other wiki pages.

There are several levels of integration:
*attachment, contains links to wiki, embed in page.
*attachment, pass through a plugin that turns simple text to cool links
*graphviz text, pass through a plugin and generate SVG
