“Graphs are like tiny dollops of science you can hold in your hand”
- First Dog on the Moon
"Above the line" voting in the Australian Senate and most State upper houses means your favourite political party can choose where preferences will be distributed, and you may not know, or like, their decisions. In 2012, Paul Foxworthy noticed that even the “how to vote” tickets for his local Council election had a long list of single-issue candidates sending second preferences to the “real” candidate.
With some analysis, you could detect clusters of candidates that seem to be co-operating. But who has the time and patience? Paul looked for, and eventually found, a way to visualise preference data.
auprefs.info is a web site and open source web application to visualise preference distribution in Australian elections. It aims to better inform voters where their vote might go. Knowledge is power - if voters can see what their vote is doing, we can hope they may be more careful how they exercise it.
Paul will talk about why he did it, and how you can create force-directed graphs and other interactive visualisations using the amazing d3 graphing library.
