What a week for interactive visualizations! Lots of good works coming from the Global Visualizing Marathon, the Hubway data visualization challenge and, if you’re still up to more infographics about the 2012 elections,Tableau’s 2012 Election Viz Gallery is worth checking out.

Among the main topics illustrated in the visualizations we collected for you today, China’s new political leadership, the Euro crisis and yet another set of graphics about the ramifications of Obama’s election.
