Mermaid.js is a powerful tool that allows you to create diagrams and visualizations using text and code. This theme has built-in support for Mermaid, making it easy to integrate into your posts.

Flowcharts

Flowcharts are excellent for illustrating workflows or decision-making processes.

graph TD; A[Start] --> B{Check Condition}; B -->|Yes| C[Perform Action A]; B -->|No| D[Perform Action B]; C --> E[End]; D --> E[End];

The chart above was generated with this simple Mermaid syntax:

graph TD; A[Start] --> B{Check Condition}; B -->|Yes| C[Perform Action A]; B -->|No| D[Perform Action B]; C --> E[End]; D --> E[End];

Sequence Diagrams

Sequence diagrams are perfect for showing interactions between objects or components.

sequenceDiagram participant Alice participant Bob Alice->>John: Hello John, how are you? loop Healthcheck John->>John: Think... end John-->>Alice: Great, thanks! Bob->>Alice: Hi Alice

Pie Charts

You can even create pie charts to show data distribution.
