Using a pre-made layout solution would indeed be optimal, no reason to re-invent wheels. Apart from the layout, we'd get the rest for free from neo4j spatial and surrounding technologies. This would be a separate visualization tool, with an ability to let clients explore massive graphs via a brows

Yeah, I think a mix of the two approaches, as Rick says, handling the selection of detail to stream via some zooming logic interactivity via SVG/JavaScript on the client is a good approach. The other is the selection of only a subset via a traversal and not zoom level on the server. That would giv

Tied in with my SVG question (which should be posted shortly), you can move some of the UI rendering to the server as well, and with SVG you could cleanly integrate data + UI elements in what is sent back to the browser. I think a mix of browser smarts to control client-side rendering (zoom levels

In this case, the graph layout could be computed server side by something like graphviz or so, and then sliced into zoom level information. Then interactivity can be added via open layers . However, of course the question is how long it takes to calculate the layout for say 100.000 nodes. After t

Intriguing option. So you assign virtual locations based on the layouting algorithm, and then use neo4j-spatial's 'export to PNG' capabilities, which also makes use of SLD for styling (geoserver-like styling, using geotools inside, of course). This is certainly not an option I had every considered,

Sorry Peter, misread you. What I was thinking was to render non-spatial graphs with neo4j spatial. A layout algorithm would calculate the "coordinates" of each node we want to visualize. That way we can view really big graphs in the browser, since the layout-work is already done by the server. Den

Yeah, you couldn't do very much with the markers. But you could pre-render millions of nodes on the server, and serve it as a spatial layer as if it was a map. Geoserver would slice it up, allowing zooming and panning just like a map. Then you would add interactivity on top of the rendered image l
