Draw a binary tree

问题

I'm looking for a js lib which allows the user to draw a binary tree : add/remove a leaf, add/remove a parent node, etc.

I've found many libs but most of them are made for data visualization only (eg: d3), not drawing from the browser.

Does this even exist ?

Thanks!

回答1:

Tree-model-js has animated example on main page by svg. You can copy and use it.

Have a look at existing stuff to draw graphs (a tree is a graph):

Pure JavaScript Graphviz equivalent

You may also write it yourself by drawing to a HTML canvas for example:
