Yes! I am very interested in this. It could become a graphical viewer/navigator for the Axiom database. I would be great to have this work through a web browser and available on the Axiom wiki. > > the layout is a challenge though. laying out endpaper took > about 4 days. > For layout I think we should depend on automatic graph layout software such as GraphViz http://www.graphviz.org I works surprizing well. We already have GraphViz on MathAction http://wiki.axiom-developer.org/GraphViz and there is an extension for LaTeX that processes GraphViz commands. There are apparently several ways to add hyperref-like links to these graphics in LaTeX but I have not had time yet to try any of these. I have just been waiting for the little extra time I would need to key in the GraphViz specification for the graphs in the endpaper.pamphlet file to see what kind of layout it will produce automatically. GraphViz is very simple to use for simple graphs and has more sophisticated options for more sophisticated graphs. For graphs that are displayed in an HTML page, GraphViz has the ability to automatically create image maps that make the graph clickable with hyperlinks in both nodes and edges.
