What is a cash flow waterfall?

A cash flow waterfall is a bar chart that walks from operating cash flow through capital expenditure to free cash flow, then shows how the remaining cash is allocated — acquisitions, buybacks, dividends, debt, and other financing — ending at the net change in cash. Each step is colour-coded: green bars add to the running total, red bars subtract.
