The document discusses using a skyline graph to compare data over time instead of pie charts. It notes that skyline graphs make it easier to see relative changes between categories and identify the biggest changes. The presentation provides examples of skyline graphs and how they better convey stories about "what happened" with data comparisons than traditional charts like pie charts.
