%K Political data visualization, roll calls visualization, political spectrum.
%X We present CivisAnalysis, a web-based system for the visualization of roll calls of Brazil's Chamber of Deputies that can give citizens a unique view of the country's political history. Covering roll calls of six legislatures as well as six presidential elections, CivisAnalysis combines roll call visualization techniques with techniques for the visualization of temporal data. In this work, we provide a visualization of roll call results as a n-dimensional space, coupling votes with the spectrum of deputies and the votes of a set of deputies with the spectrum of roll calls. We also provide a long-term political timeline integrated with election data (election results and political alliances). Our tool supports textual and visual filtering and includes auxiliary visualizations that provide an overview of the political scenario regarding deputies, parties, coalitions and their behavior along time. We also report a remote user study conducted to evaluate CivisAnalysis.
