The tree layout implements the Reingold-Tilford algorithm for efficient, tidy arrangement of layered nodes. The depth of nodes is computed by distance from the root, leading to a ragged appearance. Cartesian orientations are also supported. Implementation based on work by Jeff Heer and Jason Davies using Buchheim et al.'s linear-time variant of the Reingold-Tilford algorithm. Data shows the Flare class hierarchy, also courtesy Jeff Heer.
Compare to this Cartesian layout.

Do you have a web server running? It won't work just running in a browser. If not install something like Apache and put the files somewhere that localhost can pick them up.
I think <body> is not closed properly in index.html.
Hi, I have taken the files above "index.html" and "flare.json" and put them in a local folder. When I load index.html nothing is loading. I think it is not loading the json file for me. Is there something I am missing here?
thanks.
