Hello @mateusccoelho, welcome to the community!
Thank you so much for the contribution (and the callout 
), especially if it’s your very first venture into the frontend world. Honestly I think you took the better approach for your use cases, with vanillaJS it looks like it will be much easier to integrate Cytoscape plugins or rely on any online resources. My time with React + Cytoscape was a liiitttle bit painful I have to say, because in this specific case it was hard to map vanilla JS code to its React counterpart, which is why I did not go further on this road…
Definitely update the Components Tracker and add a line for your component.
Looking forward for the Streamlit Share app hehe.
Have a nice day,
Fanilo
