Research and choose a graph layout tool about fsml.org HOT 5 CLOSED

Had a meeting last week on this. Making progress.

from fsml.org.

@tgreen7 and @christopher-lamkin has been trying React Flow. The current focus is seeing if it could handle multiple input and output connector ports per node.

@tgreen7 has tested React Flow, it seems to be presenting basic graphs nicely!

from fsml.org.

@tgreen7 perhaps we list some of the boxes we think this tool will check off?

• Can represent a basic acyclic directed graphs
• Can accommodate multiple inputs and outputs (a la Node-RED graphs)
  requires a bit more work for custom nodes but is possible
• Can be viewed vertically or horizontally
• Can be zoomed and moved within a view
• Has a snap-to grid function for box size and location
• Has ability to move connector to different locations on the node (optional)
• Has an auto-layout function
  with a separate package (dagre) this can be accomplished.
• Compatible with generating exportable graphical representations (.pdf, .png, .svg)

I think we have provisionally chosen React Flow, So I'll close this.
