Flowchart guides
Five guides, from the basics of reading a flowchart to documenting APIs as diagrams. Start with the overview of a topic, then pick the article that matches what you are working on.
What is a flowchart?
A flowchart is a diagram that shows the steps of a process in order, using standard shapes for actions and decisions and arrows for the direction of the flow. It turns a procedure that is hard to follow in text into a path anyone can trace with a finger.
Process mapping: a practical guide
Process mapping means drawing how work actually flows from a trigger to an outcome: the steps, who does each one, the decisions and the hand-offs. A map makes the process visible so a team can agree on it, train people on it and improve it.
AI flowchart generators: from text to flowchart
An AI flowchart generator reads a description of a process, identifies the actors, steps and decisions, and draws the corresponding flowchart. It removes the slowest part of diagramming, placing and connecting boxes, so you can spend your time checking that the process is right.
Mermaid flowcharts: diagrams as code
Mermaid is an open-source tool that draws diagrams from plain text. A flowchart is written as a few lines such as "A --> B", stored next to your documentation or code, and rendered automatically by tools like GitHub, GitLab, Notion and Obsidian.
Flowcharts for APIs and software flows
Developers use flowcharts to document what code and services do in order: the calls of an API integration, the branches of an algorithm, the paths of a sign-up or payment flow. A good technical flowchart shows decisions and error paths, and names the endpoint or function behind each automated step.
