本主题已支持 `Mermaid` 实现以纯文本的方式绘制流程图、序列图、甘特图、状态图、关系图行等等，随着 `Mermaid` 也在逐步发展，后续还会有各种各样的图被引入进来，更多的类型及使用方式可关注其官方网站：[https://mermaid-js.github.io/](https://mermaid-js.github.io/)。

## 使用说明

{{< note info >}}

- 通过 `hugo new` 命令创建一篇新的文章
- 使用短代码书写各种类型的图，自带2个参数： align（对齐） 和 bc（背景色），可参考如下使用示例

{{< /note >}}

## 流程图

```shell
{{</* mermaid align="left" */>}}
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;
{{</* /mermaid */>}}
```

{{< mermaid align="left" >}}
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;
{{< /mermaid >}}

## 时序图

```shell
{{</* mermaid bc="#eee"  */>}}
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 */>}}
```

{{< mermaid bc="#eee" >}}
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 >}}
