The Wall Street Journal published its first interactive map on the 2012 election, utilizing CartoDB for data analysis and storage, which is built through CartoDB API's and the Leaflet map library. The final map summarizes the state of both the presidential and Senate race, with additional features such as projected electoral votes, economic indicators, and special filters that highlight editor's picks and senior vote trends. Readers can filter data by State and County to analyze candidate strengths and weaknesses, and a bar shows the estimated lead in each state, while also providing information on leaning and swinging states.
