After a very surprising election in which the right-wing Conservative Party won a majority government, and the left-wing New Democratic Party its greatest number of seats in Parliament ever, Canadian reporters are struggling to explain these dramatic shifts.
To this end, the Vancouver Sun has used technology from Tableau to tell this story online with data. The application shows the share of votes of the four major parties (Conservative, Liberal, NDP, and Green) as well as fringe parties and independents over elections from 2004 onwards.
This is a great way of understanding the changes in party policy, and in voter opinion. Some of the other data that would be fantastic to see on a similar chart are an average of independent polls, approval ratings, and a timeline of key political controversies.
