> Why not create the equivalent [SWI-Prolog](https://www.swi-prolog.org/pldoc/doc_for?object=manual) dict objects and leave the transformation to JSON to [json\_write\_dict/2](https://www.swi-prolog.org/pldoc/doc_for?object=json_write_dict/2)? In the HTTP server context the skeleton is typically

Yes that is one option I plan to explore but find that doing some of the parts manually at first makes it easier to understand what is happening when the need to fix problems later happens.

I am more in the experimental stage than anything right now and have never really used JSON, SWI-Prolog dicts or Cytoscape.js to a level that I feel comfortable so this is like doing lots of homework problems to learn.

I didn’t even know json\_write\_dict/2 existed until just yesterday when trying to answer this other [question](https://swi-prolog.discourse.group/t/convert-atom-to-term-give-me-another-value-the-atom-value-is-a-variable/2820).

There is also the code by CapelliC ([GitHub - CapelliC/swish\_cytoscape\_js: SWISH graph rendering by means of cytoscape\_js](https://github.com/CapelliC/swish_cytoscape_js)) which I want to better understand.
