What is a Galaxy Chart?

A Galaxy Chart is a significant advance in data visualization that enables easy and effective presentation of data organized in a hierarchical, element structure. A Galaxy Chart depicts all levels of the hierarchical data in a single chart, clearly illustrating proportions, magnitudes, and relationships among individual data elements. Each element is represented by its own circle and all relationships between circles are illustrated using straight lines. All circles are sized proportionally by area and are arranged in a decreasing, clockwise manner.

Galaxy Charts are different and better than other chart types, such as Pie Charts, because they enable the effective presentation of several levels of data and all element-to-element relationships in a single chart. This unique aspect of Galaxy Charts offers the ability to interpret data in a more meaningful fashion, one that enables insight into what’s really important for making the most informed decisions.
