`mermaid` shortcode 使用 [Mermaid](https://mermaidjs.github.io/) 库提供绘制图表和流程图的功能.

<!--more-->

[mermaid](https://mermaidjs.github.io/) 是一个可以帮助你在文章中绘制图表和流程图的库, 类似 Markdown 的语法.

只需将你的 mermaid 代码插入 `mermaid` shortcode 中即可.

## 1 流程图 {#flowchart}

一个 **流程图** `mermaid` 示例:

```markdown
{{</* mermaid */>}}
graph LR;
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
{{</* /mermaid */>}}
```

呈现的输出效果如下:

{{< mermaid >}}
graph LR;
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
{{< /mermaid >}}

## 2 时序图 {#sequence-diagram}

一个 **时序图** `mermaid` 示例:

```markdown
{{</* mermaid */>}}
sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->John: Fight against hypochondria
    end
    Note right of John: Rational thoughts <br/>prevail...
    John-->Alice: Great!
    John->Bob: How about you?
    Bob-->John: Jolly good!
{{</* /mermaid */>}}
```

呈现的输出效果如下:

{{< mermaid >}}
sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->John: Fight against hypochondria
    end
    Note right of John: Rational thoughts <br/>prevail...
    John-->Alice: Great!
    John->Bob: How about you?
    Bob-->John: Jolly good!
{{< /mermaid >}}

## 3 甘特图 {#gantt}

一个 **甘特图** `mermaid` 示例:

```markdown
{{</* mermaid */>}}
gantt
    dateFormat  YYYY-MM-DD
    title Adding GANTT diagram functionality to mermaid
    section A section
    Completed task            :done,    des1, 2014-01-06,2014-01-08
    Active task               :active,  des2, 2014-01-09, 3d
    Future task               :         des3, after des2, 5d
    Future task2               :         des4, after des3, 5d
    section Critical tasks
    Completed task in the critical line :crit, done, 2014-01-06,24h
    Implement parser and jison          :crit, done, after des1, 2d
    Create tests for parser             :crit, active, 3d
    Future task in critical line        :crit, 5d
    Create tests for renderer           :2d
    Add to mermaid                      :1d
{{</* /mermaid */>}}
```

呈现的输出效果如下:
