## The Rendered Diagram May Appear Smaller Than Expected

When rendering diagrams using `markdown-it-kroki`, you may notice that the output appears smaller than expected.  
This issue can be resolved through CSS styling.  

For example, consider the following Markdown code:

    ```mermaid[mermaid image]
    graph TD
    A[ Anyone ] -->|Can help | B( Go to github.com/yuzutech/kroki )
    B --> C{ How to contribute? }
    C --> D[ Reporting bugs ]
    C --> E[ Sharing ideas ]
    C --> F[ Advocating ]
    ```

When using markdown-it-kroki to render this Markdown, the output will be:

```html
<embed title="mermaid image" src="https://kroki.io/mermaid/svg/....">
```

To adjust the size of the rendered diagram, you can define the following CSS:

```css
embed[title="mermaid image"] {
    width: 500px;
    height: auto;
}
```
