Abstract: In this work, we present CivisAnalysis, an open-source web-based system for the visualization of roll calls in the Brazil’s Chamber of Deputies. Using roll calls of six legislatures as well as six presidential elections, CivisAnalysis provides a unique view of the political history of our country. It combines classical roll calls visualization techniques with techniques for the visualization of temporal data. Votes of each representative are interpreted as a set of multidimensional data, which are represented in a n-dimensional space mapped to a bi-dimensional representation. The Votes of each representative determine their position in the political spectrum of deputies, and the votes of all deputies determine the political spectrum of roll calls. The work also shows how exploring subsets of deputies allows the discovery of voting patterns in the roll call spectrum, as well as exploring the roll calls spectrum allows the discovery of behavioral voting patterns in the political spectrum of deputies. For supporting a long-term political analysis, CivisAnalysis provides a time line visualization integrated with election data (election results and political alliances). The tool implements 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.
