"The heart of our work at the Pew Research Center is data. And data visualizations that tell clear stories about our research — whether it be about American politics or our changing demographics — are just as important as the words we write in a report. So, what makes a successful data visual? We think it should present information clearly and concisely, engage the reader and allow them to explore that information.
This year, the design staff looked back through our 2014 archive, and these graphics stood out as almost universal favorites. These visualizations presented a particular challenge and, for each of them, we talk about the approach we took in presenting the data."
