Arboreal is a Firebug UI enhancement which adds a HTML sidepanel for DOM tree visualization.
Watch a screencast!
The algorithm to produce the tidy node-link tree layout is that of Christoph Buchheim, Michael Jünger and Sebastian Leipert from their research paper entitled 'Improving Walker's Algorithm to Run in Linear Time', Graph Drawing 2002.
- Seemlessly integrates into current version of Firebug (1.6 for Firefox 4)
- Visualizes DOM tree structure in HTML sidepanel
- Synchronizes with Firebug, especially its page inspector
- Has configurable DOM tree layout, e.g. you can
- hide DOM node element names in graph nodes to fit larger trees in panel
- change color schemes (HTML tag groups, DOM node tree depths, DOM tree leaf nodes,...)
- change the orientation of tree (top-to-bottom, left-to-right, right-to-left, bottom-to-top)
- extract and re-insert DOM node subtrees
- choose to expand or collapse DOM text, comment and iframe nodes
- Provides intuitive navigation in DOM tree visualization (by keyboard and mouse)
- Shows popups with element content preview
- Provides collapsed tree traversal, i.e. conditional subtree expansion
- Generates of AT&T GraphViz files for current DOM tree view
