Modern visualization tools aim to let data analysts easily create exploratory visualizations. When the input data layout conforms to the visualization design, we can easily specify visualizations by mapping data columns to visual properties of the design. However, when there is a mismatch between data layout and the design, we need considerable effort on data transformation.

Falx is a visualization-by-example tool to address this challenge. Falx lets users demonstrate how a few data points should be visualized, and it automatically generalizes…
