The oval symbol in flowcharts represents the start and end of the process. It is commonly used to indicate the beginning and conclusion of the flowchart. Digital diagramming tools often provide the option to easily add the oval shape to the document through drag and drop functionality.


Process (The Rectangle)

In flowcharts, the rectangle symbolizes the process steps involved in the diagram. It is commonly used and considered the workhorse of flowchart symbols. This shape is ideal for representing actions and basic steps within the process.


Flow Line (The Arrow)

An arrow is part of the many flowchart symbols to guide your audience along the flowcharting journey. You can use different kinds of arrows, but deciding on one or two for the entire diagram is recommended. It lets you make your flowchart clean and emphasize the steps in your process.

Decision (The Diamond)

Diamonds in a flowchart indicate that a decision point has been reached, requiring a choice to proceed.
