    Here's Jesus' reply to a question on SVG; we may be able to help him out
    in some sort of cooperative venture. I don't think the GUI is the prettiest
    thing, but it seems to work quite well. He's planning on adding the ability
    to change the vertex symbol, so we could have both rectangles and ellipses
    for displaying topic maps (or CGs). We might even be able to get someone
    to write an XSLT stylesheet to transform from XGMML to SVG (though that
    seems like it might be pretty difficult). wrote:
