I should be able to see a graphical representation of single package size broken down by directory and file. This graphical representation should be linked to the total package size one (see bug 4330).

The visualisation method is TBC, but we could consider 

* treemaps 
* treemap variations (like Voronoi diagrams) 
* polar area diagrams
* quartiles table

Or a combination of 2 or more of the above. 

The graph(s) should be interactive (zoom, pan, hover over sections to display information and click sections to drill down into a directory). 

I should also be able to hide the graph(s).

For a good treemap example see:

For a Voronoi diagram example see:

For a polar area diagram example, see:

I've attached an image of a quartiles table built with Excel (see quartiles_table_excel.png). You can download the original file from
