I am looking for a web library/framework that would allow me to place nodes on a diagram, link them with "tubes" and somehow visualize flow between the nodes. I am only looking for the visualization part. Does such thing exist?


Essential Diagram for JavaScript supports creating any kind of diagram with nodes and connectors. The library is not open source, but a community license is available (details below)


Diagram JS with animated connectors

The whole product is available for free through the community license if you qualify (less than 1 million USD in revenue).

I work for Syncfusion.
