Storyboarding

Storyboarding is used to help develop visualizations during the early stages and to help troubleshoot hard to visualize concepts. Storyboarding takes the form of 'sketches' either created on the computer or by hand. The goal is to create a series of quick images which represent the key concepts happening over time in an animation (or location in a static visualization). Each image will capture the 'action' at a point in time, only representing the key forms and rendering elements. The goal is to allow the visualization team to explore various ways of concept without committing the time necessary to create a finished visualization.
