the prefuse visualization toolkit

If I understand you right, you don't know how to change the point, where exactly an edges arrowhead is sticked/fetched/attached (don't have the adequate english word at hand :)) to the target item. Like if the edge should point to the lower right corner of the target item or to the middle left part, etc?

If that's the case, you need to overwrite the EdgeRenderer and modify the target location in respect to the current items "business logic".

If I didn't get you right, please be more precise, possibly with a minimal example. (Ok, I'm off for this weekend.)

hope that helps, Björn
