Diagrams

Add various diagram types, including flowcharts, decision trees and entity-relationship diagrams.

Diagrams are powerful tools for visualizing processes, relationships, and decisions. This section showcases different types of diagrams created using Mermaid, complete with examples and reusable code snippets to integrate into your projects.

Flowchart

A flowchart represents a sequence of steps or processes in a visual format. Use this diagram to map workflows, decision-making processes, or operational flows.

<Mermaid chart="graph TD
Start --> Task1
Task1 --> Task2
Task2 --> End" />

Decision Tree

Decision trees illustrate choices and possible outcomes, making them ideal for decision-making workflows or processes involving multiple paths.

<Mermaid chart="graph TD
  A[Start] --> B{Is it raining?}
  B -->|Yes| C[Take an umbrella]
  B -->|No| D[Enjoy the weather]
  C --> E[Go outside]
  D --> E" 
/>

Entity-Relationship Diagram

Entity-relationship diagrams (ERDs) are used to model relationships between entities in a system. They are widely used in database design and system architecture planning.

<Mermaid chart="erDiagram
  CUSTOMER ||--o{ ORDER : places
  ORDER ||--|{ LINE-ITEM : contains
  PRODUCT ||--o{ LINE-ITEM : included in
  CUSTOMER {
    string name
    string email
  }
  ORDER {
    int orderNumber
    date orderDate
  }
  LINE-ITEM {
    int quantity
    float price
  }
  PRODUCT {
    int productId
    string name
    float price
  }" 
/>

Each of these diagrams serves a specific purpose and Mermaid makes it easy to generate them dynamically. Feel free to experiment with the provided code snippets and adapt them to your needs.
