Hi,
I'm new to RoR and just wondering if there is a plugin/component (ajax
based) for rails drawing a sitemap, which look like some kind of diagram.
                     |---------|
                     |         |
                     |         |
                     |---------|
                          |
       --------------------------------------------------
       |                |                |              |
  |---------|      |---------|      |---------|    |---------|
  |         |      |         |      |         |    |         |
  |         |      |         |      |         |    |         |
  |---------|      |---------|      |---------|    |---------|

At the begining it's all colapsed, and after clicking in boxes, new
nodes appears. It's important not to load everything at a begining.
Further boxes should be loaded when they are needed (AJAX)
Have you guys heard something about it?

thanks
