为博客添加Mermaid图表支持及其使用
使用jekyll插件
可以使用 Jekyll-mermaid，Mermaid官网还写了一个插件jekyll-mermaid-diagrams，但如何使用没有写。这两个插件都好久没更新了。
Installation
- Install the gem:
gem install jekyll-mermaid
- Add the gem to your Jekyll _config.yml:
gems: [jekyll-mermaid]
Config
You’ll need to update your _config.yml with the location of the mermaid source javascript file you want to use.
mermaid:
src: 'path/to/mermaid.js'
Usage
Simply include the jekyll-mermaid block helper in any of your templates.
{% mermaid %}
graph TD;
A-->B;
A-->C;
B-->D;
C-->D;
{% endmermaid %}
直接使用HTML引用JS文件
