This document discusses how to create PivotDiagrams in Visio2007 to visualize and analyze data from Excel or a database. It describes a 3 step process: 1) insert a PivotDiagram, 2) link it to a data source, and 3) expand the Pivot Node to show different levels of data. PivotDiagrams allow users to dynamically link drawings to data for faster and easier analysis compared to static diagrams. Data graphics elements like text, data bars, and icons can then be used to represent different fields and metrics from the data set.
