Jo wrote some code (http://mappinghacks.com/openguides/) to do an SVG plot of where nodes with lat/long data are in relation to each other. I've modified it a bit to highlight stations to give an idea of scale, and here's the result:

Stations are red, other nodes are blue. It's crude, but you can pick out several different Tube lines and see where the big clusters of nodes are.

i think this is definitely very cool, and that around the edges you can see how peoples perception of london is oriented to tube islands, pretty clearly, blue nodes cluster within walking distance of red dots.
i'd love to do a rewrite or mapping specialisation of SVG::Plot, which is really starting to show its age and our relative inexperience a bit. I'm hopefully doing some work on the consume.net nodedb and would love to dual-purpose for openguides and other community mapped data resources, too.
as muttered on irc i think it'd be fairly easy to do zoom invariance on the nodes so they don't become big bubbles as you zoom in, and that could be an easy start. also earle suggested overlaying an OG node map on this: http://space.frot.org/rdf/tubemap.svg but that's not SVG::Plot compatible.
perhaps a little geo BOF at the putative OG hacksesh soon?
