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.
