Nice work! I've been looking for a lightweight lib for tree visualizations in JS. I'm excited to try this out with my current project. Thanks for sharing!

Agreed, really clean code! Forgot to ask, what's the licensing model for this lib?

Really enjoying trying this lib out, and bonus points for being lightweight! Keep up the good work :)

Hey! I like it, but I noticed it's lacking support for drag-and-drop functionality for nodes. Could this be a potential feature request?
darksteel 1 year ago next
Thanks! Yeah, a drag-and-drop feature is definitely a great idea; I've added it to the Trello board under feature requests. Happy coding.

Looks good, this is definitely something I would use. Good job on the zooming functionality as well!

Will there be any support for loading tree structures from external sources (e.g. JSON files, APIs)? It would be an awesome feature to have.
darksteel 1 year ago next
That's a good point, and yes, I am planning on adding external loading options in a future version. I'll be sure to update everyone here on HN once I've got a working prototype up on GH.

I noticed the library is under MIT License. Super appreciated!

Hi @darksteel, how does the performance of this lib compare against similar libraries for large datasets (10,000+ nodes)?
darksteel 1 year ago next
@G1etz For large datasets, it'll depend on the configuration and hardware handling the rendering. This library's implementation uses canvas, which in theory could perform better than DOM manipulation; however, this would heavily depend on the device it's being rendered on. I personally haven't tested it with datasets larger than 1000 nodes.

Nice lightweight lib! I was pleasantly surprised to see that it doesn't require the use of any additional HTML tags to render the tree structures.

Any support for rendering of different shapes other than the default circles? Implementing an arc-based structure could be useful.
darksteel 1 year ago next
Great suggestion! I like the idea of adding more shapes, ideally so it accommodates SVG as well for better flexibility in shaping nodes. I'll be sure to update you folks when I add this feature. Cheers!
