Quartz supports Mermaid which allows you to add diagrams and charts to your notes. Mermaid supports a range of diagrams, such as [flow charts](https://mermaid.js.org/syntax/flowchart.html), [sequence diagrams](https://mermaid.js.org/syntax/sequenceDiagram.html), and [timelines](https://mermaid.js.org/syntax/timeline.html). This is enabled as a part of [[Obsidian compatibility]] and can be configured and enabled/disabled from that plugin.

By default, Quartz will render Mermaid diagrams to match the site theme.

> [!warning]
> Wondering why Mermaid diagrams may not be showing up even if you have them enabled? You may need to reorder your plugins so that `Plugin.ObsidianFlavoredMarkdown()` is _after_ `Plugin.SyntaxHighlighting()`.

## Syntax

To add a Mermaid diagram, create a mermaid code block.

````
```mermaid
sequenceDiagram
    Alice->>+John: Hello John, how are you?
    Alice->>+John: John, can you hear me?
    John-->>-Alice: Hi Alice, I can hear you!
    John-->>-Alice: I feel great!
```
