Link or Path Types

[edgebender]

I'd like to be able to define different links between nodes, but am not an expert at D3 or JS.
Would it be possible to select a SVG to act as the link from node to node.
This would be used to represent message queues, SOAP, or microservices, etc. between nodes.

You can use different colors or different width for the links, but not images.
