Summary  
The chapter explains how to implement stacked bar and area charts by layering multiple data series to visualize both cumulative totals and individual contributions.

General domain of usage  
Dashboard data visualization

Stacked charts provide a powerful way to visualize cumulative data in dashboards. By layering multiple data series on top of each other, stacked bar and area charts make it easy to compare both the total value and the individual contributions of each category. This approach is especially useful when you want to track how different components add up to a whole, such as sales by product line over time, or energy consumption by source. In a dashboard context, stacked charts help you quickly spot trends, identify dominant categories, and understand overall composition at a glance.
