A flowchart is a diagram that visually represents a process, system, or computer algorithm using standardized shapes connected by arrows to show the sequence of steps. It uses symbols like rectangles for processes, ovals for start/end points, and diamonds for decisions to break down complex tasks into a clear, step-by-step format. Flowcharts are used for planning, documenting, and understanding workflows and algorithms.

Key components and their descriptions

Process: A rectangle represents a step, action, or operation within the process, such as "add 1 to the input".

Terminal: An oval shape indicates the start or end of the process or algorithm.

Decision: A diamond shape represents a point where a decision is made, often with a "yes" or "no" or "true/false" outcome, branching the process into different paths.

Input/Output: A parallelogram shows data entering (input) or leaving (output) the system.

Flow line: Arrows connect the symbols to show the direction of the process's flow and sequence.

Document: A rectangle with a wavy bottom represents a document being used in the process.

Off-page connector: A small circle indicates where a flowchart continues on a different page.
