A run chart is a simple graphical representation of a series of data points over a period of time. It is used to observe trends, patterns, or shifts in the data, which can help in identifying process variations or improvements. Unlike some other tools, it does not specifically indicate relationships between variables or directly control process variations but rather visually displays the performance or behavior of a process over time.
