TreeMapping is an ingenious means of visualising hierarchic values. Often used to answer the question "Where has all my disk space gone?" it lends itself naturally to many data models, even if the hierarchy is artificial.
jsTreemap does all this in plain old JavaScript and HTML DIV elements. The treemap control can be fully interactive and allows the user zoom in and out.
The Treemap can also make use of an adapter object to fit existing (and sometimes large) data models, in an XML DOM for example.
