I'm working on a project where I need to render diagrams in the browser similar to this:
I've looked at a number of organisational charting tools such as the Google Visualisations Organisation Chart but none of them seem to let me change the orientation.
The nodes shown in the diagram above don't have to be icons, in fact I'd prefer to work with just plain old boxes where I can inject a snippet of HTML (in the same way you can do with the Google Visualisations Organisation Chart).
It would also be useful to be able to highlight a specific path through the chart, as the green lines in the example above do.
Does such a library exist?
The one I've used before is The JIT, and it was pretty good. You'll probably want to investigate and make sure it meets your requirements though. For me it didn't quite fit because I needed to show multiple paths to the same node, which it couldn't handle (at least at the time). But it was a good visualization tool and was fairly easy to use if I remember correctly.
