Video demonstration from the 1999 CHI conference. Multiple studies have shown that clutter or sparsity in visual representations can have negative effects ranging from decreased user performance to diminished visual appeal. We have developed a system that assists users in the construction and navigation of visualizations with appropriate visual information density. This system, VIDA (Visual Information Density Adjuster), applies a cartographic principle to minimize clutter and sparsity in visual displays of information.
