How to get the canvas element of a force-graph instance?

[GwokHiujin]

Hello, this project is really excellent and useful! Thank you very much for developing it. ✨

I'm recently deploying it in my own project and trying to add an "export as image" feature to it. Since the image is rendered in a canvas element, I think I need to use a method like toDataURL to do the export, but I can't find a corresponding interface that allows me to get the canvas element in the page. Is there a method I can call?

@GwokHiujin thanks for reaching out.

If you have a reference to the DOM element where you mounted the graph (f.e. myElem), you can simply query for a child canvas element, like so:

myElem.querySelector('canvas')

Thank you for your reply! This solves my problem nicely :)
