This is a visualisation of the preferences in the Group Voting Tickets submitted by political parties for the Victorian Legislative Council (upper house) Northern Metropolitan region election held on Saturday, 29 Nov 2014.
Interpreting the graph
Float your mouse over a party to see their own preferences.
The closer the circles are for two parties, the more similarity in outlook, as determined by the preferences of all parties. So overall positioning of parties reflects everybody's view of everybody else. For example, in the Western Australia Senate election in April 2014, the Liberals and Nationals appear right next to each other, because they preferenced each other, and all other parties put them very close together on their own preference lists.
The blue arrows highlight what we call funnels: parties that are receiving second preferences from more than one other party. In other words, a party is giving second preference to another party without getting a second preference in return.
