Anyone know of any good diagramming/network-type graphing components? Basically, I am looking for something that allows me to define nodes (shapes, icons, etc) that can be dragged/dropped from a pallet onto a canvas (not meaningFlex Canvas component). Those nodes can be moved around and connected, etc.
I have seen one from KapIT called "Diagrammer", which is one possibility. I have also seen yFiles (www.yworks.com), which is a fairly pricey pay-component. Preferably the component would be free and open-source but not required. Any other ideas or thoughts?? I have seen this functionality in demos/examples online, but I'm wondering if each shop is rolling their own.
