Voyager 2 is a data exploration tool that blends manual and automated chart specification. Voyager 2 combines PoleStar, a traditional chart specification tool inspired by Tableau and Polaris (research project that led to the birth of Tableau), with two partial chart specification interfaces: (1) wildcards let users specify multiple charts in parallel,(2) related views suggest visualizations relevant to the currently specified chart. With Voyager 2, we aim to help analysts engage in both breadth-oriented exploration and depth-oriented question answering. For a quick overview of Voyager, see our preview video, or a 4-minute demo in our Vega-Lite talk at OpenVisConf, or watch our research talk at CHI 2017. For more information about our design, please read our CHI paper and other related papers (1, 2, 3).
