Arranging only a subset of the graph nodes in a particular layout using cytoscape.js

Question

Cytoscape JS offers an interesting feature called LAYOUTS. I want to arrange a collection of nodes in a circular layout. But I do not want all the nodes of my network graph to lie on that circle.

How can I do this using cytoscape.js?

Additional Explanation (optional)-

Here is an example I built using Arbor JS, which I am considering re-implementing using Cytoscape in a fixed manner, showing all nodes at once.- Cluster-Mapping

I want just the Nodes (orange dots) to be represented on a circle and NOT the Instances (brown rectangles) that appear on hovering in this arbor based example.

Answer 1

This is now possible with eles.layout() (version 3.7).

Refer to the documentation: eles.layout()

Answer 2

This is a planned feature. I created a ticket for you to track its progress. https://github.com/cytoscape/cytoscape.js/issues/295
