Draw a circle around a node with an arrow at one end

Question

I would like to be able to draw a circle around a label/node with an arrow head at one end.

This is so that I can produce System Dynamics drawings, they are required to show if a feedback loop is either balancing or reinforcing.

Regards, Ed

Answer 1

Create a small cirlce node (e.g. 10x10). Start a polyline edge at that node. Make sure not to create any bends in the edge and use the start node as target node, too. Use the automatically created bend to adjust the loop size to your needs. Select the circle node and set "Fill Color" and "Line Color" to "No Color". Finally, place where needed.

Sample feedback loops.
