js-treemap

Js-treemap is a fantastic JavaScript implementation of treemaps that offers users an incredible means of visualizing hierarchic values. Its primary use-case is to help users answer the question of where all their disk space has gone, but it's flexible enough to work with many different data models, even artificial hierarchies.

One of the most significant benefits of jsTreemap is that it's built using plain old JavaScript and HTML DIV elements, making it easy to use and remarkably lightweight. The treemap control is fully interactive, and the user can zoom in and out, providing an even greater level of detail.

Another great feature of jsTreemap is its adapter object, which lets users fit existing data models, even large ones, into the treemap's hierarchy. This is particularly useful when working with XML DOM-based models.

While not an exhaustive list, jsTreemap has been successfully tested and run on several platforms, including Firefox v2.0, Internet Explorer v6.0, Safari v3.1 on Mac OS X, and even Opera on Nintendo Wii.

Overall, if you're looking for a powerful, flexible, and easy-to-use treemap implementation, jsTreemap definitely deserves your attention. Its versatility and adaptability make it a go-to tool for anyone who needs to visualize or analyze hierarchies in their data.
