Info

Explore the 2010 US budget. To move the pie chart use the mouse to drag the chart and/or use the mouse wheel to scroll through the chart. Click for zoom levels using the buttons.

Motivation

I wanted to make a pie chart to explore the US 2010 budget. Realizing that the budget has many large and small parts which would be hard to show properly, it was required to look at one part of the pie at a time, so I made this rotating pie chart.

Tools

Protovis, jQuery, FancyBox

Results

I’ll be first to admit that this didn’t turn out how I wanted it to. The text is too small, but it’s hard to look at this properly at the smallest levels. Maybe it would be easier to remove the largest parts (National Security and Social Security) since those don’t have interesting subsections.

I would like to add proper colors which match for the first level and second level nodes.

• The data used for this pie chart was from What We Pay For for 2010 budget. I noticed some negative values and I need to investigate the reason for those. Data for all data in JS variable for Protovis.
• SVG Image for By Function and on webpage, and By Subfunction.
• Another image version with just nodes that provide more information shown made.
