Flow Chart Symbols. You'll notice that the flowchart has different shapes. In this case, there are two shapes: those with rounded ends represent the start and end points of the process and rectangles are used to show the interim steps. These shapes are known as flowchart symbols. There are dozens of symbols that can be used in a flowchart.
