I'm trying to add a custom layer on top of OpenLayers that shows tags (think something like http://tagmaps.research.yahoo.com/worldexplorer.php this ) plus a bit of interactive data visualization. I've done some experimenting with Raphael.js and the JavaScript InfoVis Toolkit. Worked quite well. However so far, I placed my graphics in a separate DIV, which I placed on top of the OpenLayers DIV. Syncing this DIV with the map when zooming/panning got quite messy (and the mouse event handling, too...)
Ideally, I would like to pack all this stuff into a 'real' OpenLayers layer. However I don't really know where to start for building this as a custom layer type. Any pointers much appreciated! Thanks!
