Visualize changes in Australian Federal Government department staffing levels using a Treemap

Australian Federal Budget 2014/15: Changes to Public Service Staffing Levels

A treemap is used to display the hierarchy of Federal Government ministries and departments. The size and colour of the rectangles encode the number of staff (2013/14 or 2014/15) and the change in staffing levels (absolute or percentage), respectively.

Source data comes from Budget Paper 4 Table 2.2 Average Staffing Table.

The treemap was implemented using D3.js, and borrowed heavily from a couple of excellent examples:
