This document discusses the use of graphical vs textual information in dashboards. It provides examples showing that graphical representations of data, such as charts and graphs, allow users to more quickly understand relationships and boundary conditions compared to textual/tabular representations. Specifically, graphical formats allow users to immediately see the highest or lowest values, compare two datasets against each other, and get a quick summary of metrics over time. The document recommends using graphical information in dashboards to make data more easily understood and to enable more informed decision making.
