Flowcharts are one of the most widely used diagram types in the world. They help students understand processes, assist businesses in improving workflows, and enable developers to visualize logic before writing code. Whether you're documenting a system, planning a project, or teaching a concept, flowcharts make complex ideas easier to understand.
With SmartWayze’s free online Flowchart Maker, you can create clean, professional flowcharts directly in your browser — no installation, no account, and no learning curve. This guide will walk you through everything you need to know about flowcharts, including symbols, rules, examples, and best practices.
A flowchart is a visual diagram that shows the steps of a process in sequential order. Each step is represented by a shape, and arrows show the direction of flow. Flowcharts are used in:
Flowcharts simplify communication by turning text‑heavy explanations into clear, visual sequences.
Flowcharts use standardized symbols to represent different types of actions. Here are the most common ones:
Shape: Rounded rectangle
Purpose: Indicates where the process begins or ends.
Shape: Rectangle
Purpose: Represents a step or action.
Shape: Diamond
Purpose: Represents a yes/no or true/false decision.
Shape: Parallelogram
Purpose: Shows data entering or leaving the system.
Shape: Circle
Purpose: Connects different parts of a flowchart.
Shape: Wavy‑bottom rectangle
Purpose: Represents a document or report.
Shape: Double‑lined rectangle
Purpose: Represents a sub‑process or function.
SmartWayze includes all these symbols in its drag‑and‑drop stencil library, making it easy to build flowcharts quickly.

Before adding shapes, decide what process you want to visualize. Ask yourself:
Drag a terminator shape onto the canvas and label it “Start.”
Use rectangles to represent actions. Keep labels short and clear.
Use diamonds to represent choices. Each decision should have two arrows:
Use arrows to show the flow of the process. SmartWayze’s connectors snap neatly to shapes.
Finish your flowchart with a terminator labeled “End.”
SmartWayze allows you to export your diagram as:
Here’s a simple example to illustrate flowchart structure:
This simple example demonstrates how decisions branch into different paths.
Avoid unnecessary shapes or overly long labels. Simplicity improves readability.
Uniform shapes make your flowchart look clean and professional.
Most flowcharts flow top‑to‑bottom or left‑to‑right. Avoid mixing directions.
Crossing connectors make diagrams confusing. Rearrange shapes to avoid overlaps.
Color can highlight important steps, but too much color becomes distracting.
Always label arrows coming out of decision diamonds.
Use spacing or color to group similar actions.
Use predefined process symbols to represent complex steps that have their own flowcharts.
Swimlanes divide a flowchart into sections representing different roles or departments.
Use split arrows to show tasks that occur simultaneously.
Loops represent repeated actions, such as “Retry until successful.”
