I have to draw a graph with many nodes, and I thought that an user interface like what Google maps offers could be nice to navigate the graph. I’m currently using Java for my application (a web application): what technologies/libraries should I use to build an interface like google maps? What approach?
edit: I’m interested mainly in creating a draggable map with zooming capabilities
edit2: I’m not looking for the exact solution of the problem, but for some starting point
Are you familiar with OpenLayers? It is JavaScript map visualization library. Combined with something like OpenStreetMap, you can get some very powerful visualization with data for free.
