A simple static HTML page using JavaScript Canvas to draw recurisive tree. Click here to see the final result.
How does it work
In it's essence, index.html is responsible for providing tree-drawing configuration by placeing initial tree trunk somewhere on the page.

The core trick is that the beginning of each new branch derived from the end of it's predecessor.
