In a flow chart, what does a circle indicate?

In flow charts, a circle typically indicates a start point. This symbol is used to designate where the flow of the process begins, helping to outline the initial step in a series of actions or decisions. The use of a circle for this purpose creates a clear and visually distinct marker that guides the reader through the flow of the chart.

While other shapes represent different aspects of the flow chart—such as diamonds for decision points and rectangles for process steps—circles are specifically reserved to highlight the initiation of the flow. This understanding is fundamental in reading and constructing flow charts effectively, as it ensures clarity about where processes commence.
