Rado, Here are a couple of graph editors to look at: 1. http://graphexploration.cond.org/test.html This is from Trac #1320. Java applet, you can pan easily (drag a location in empty space), clicking on a vertex zooms you in (Display > Center menu item is one way to get back out). Rolling over edges seems to highlight endpoints and their labels. GPL'ed but not updated since about two years ago. 2. http://buzzard.ups.edu/gts/testing.html This is a standalone Java program I wrote years ago to explore properties of graphs. It never quite made it to prime time. This page with demo applets works for me still (amazingly), using 64-bit Sun Java 6 on KUbuntu in Firefox. YMMV. Screenshot of full program at http://buzzard.ups.edu/gts/screenshot.jpg Two blank canvases at the top. Click to make vertices, read instructions just below for more. Try right-clicking on vertices and edges to experiment with coloring vertices or edges. Another applet at the bottom illustrates my idea of "drop-in" computational boxes (you may need to move a vertical separator to expose the graph editing window on the left side). As a demonstration, one such box just counts triangles, updating itself as you edit the graph. I think this sort of functionality would be easy to accomplish with a good graph editor and additions to the @interact functionality. 3. There's been a rumor about that Mike Hansen was experimenting with graphs in SVG format. More later.
