Waterfall chart

Definition

A waterfall chart is a data visualization tool that helps to display the cumulative effect of sequentially introduced positive or negative values. It visually breaks down the contribution of various components to a total, making it easier to understand how an initial value is affected by a series of intermediate positive and negative values leading to a final result. This type of chart is particularly useful for financial analysis, helping stakeholders visualize how a starting point, such as revenue, is impacted by costs, expenses, or other factors over time.
