1.) Display about 5000 nodes & edges
2.) add or delete nodes/edges from the graph
3.) click nodes/edges on the graph & execute a custom callback function
4.) Provide a blank overlay behind the markers so it is not obvious that this is a Google Map
I built this using gwt-maps-v2, but it performs very slugglishly. Load time is slow, the elements take a while to reappear on pan/zoom, and the blank background flickers on pan/zoom. I have seen solutions for this using javascript such as GMarker and MarkerLIght.
Is there anything similar for GWT?
