Version: 0.3.1, updated 25 September 2012
ProD (=Prototype Dendrograms) is tool for visualizing linguistic tree structures, e.g. constituent structures, dependency structures, language family trees, etc. In addition to the basic drawing, the library allows for interactive searching and highlighting of the structure, as well as collapsing a subtree by clicking on its parent. Despite the name, ProD will layout the structures either as dendrograms (nodes horizontally aligned by their distance from the leaves) or as node-link (tree) diagrams (nodes horizontally aligned by their distance from the root).
Here are a few sample uses:
ProD is still very much under development, with only in-line documentation. Any feedback is appreciated.
ProD has been tested with Chrome, Firefox, Opera and Safari on OS X 10.6. There are occasional issues with redrawing the same tree with a different layout in all but Firefox.
refresh() in Variations and searching for a workaround.
