A sprint burndown chart tracks the amount of remaining work in an agile sprint over time, plotted as a step (or line) series that descends as tasks are completed. A straight ideal-burndown guideline runs diagonally from the total committed scope on day one down to zero on the final day, giving the team an at-a-glance reference for whether they are ahead of or behind schedule. It is one of the most widely used project-management visualizations in software development, surfacing scope creep, stalled progress, and end-of-sprint risk early enough to act on.
