SketchInsight: Telling Stories with Data via Freeform Sketching - Microsoft Research.
SketchInsight is an interactive whiteboard system for storytelling with data by using real-time sketching. Creating personalized, expressive data charts becomes quick and easy. The presenter simply sketches an example, and SketchInsight automatically completes the chart by synthesizing from example sketches.
This new whiteboard technology could be very helpful, but I'm curious to understand exactly how much data wrangling is necessary.
