Visual exploration and analysis of data is increasingly important for advancement in virtually every area of human endeavor. Whether recorded directly by people or indirectly using machines, data captures our observations and interpretations of the world.

When people interact with data, it is almost always in a visual form like graphics or text. The goal of this project is to vastly expand the usefulness of interactive visualizations by providing a general way to create and edit data inside the visualizations themselves.

The key new idea of the project is that visualization users can perform sequences of gestures with common input devices to express their observations and interpretations directly in visual form. The visualizations not only show data, but also serve as meaningful graphical spaces in which to edit that data.
