A flow diagram is a powerful tool for visually representing an algorithm. It uses various shapes and arrows to illustrate the sequence of operations and decisions within the process. Each shape denotes a different type of action, such as starting or ending a process, performing calculations, or making decisions, allowing anyone reviewing the diagram to easily follow the logical flow of the algorithm.

This clarity and structured format make flow diagrams particularly effective for understanding complex processes and debugging algorithms, as they lay out the steps in a linear and concise manner. Additionally, the visual aspect helps learners and stakeholders grasp the workflow at a glance, facilitating communication and collaboration among team members.

While data flow diagrams do focus on the flow of data within a system, they are designed for data processing rather than step-by-step algorithms. Charts and spreadsheets serve different purposes, such as organizing data or calculations, rather than explicitly detailing the flow of an algorithm’s logic.
