Description

Close #6385
Added support for drawing with ECharts during output, which can directly output interactive images.
Use Json format for transmission in Markdown, just convert the information in option into json format and pass it in.

Example:

Code 

```echarts
{
  "xAxis": {
    "type": "category",
    "data": ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
  },
  "yAxis": {
    "type": "value"
  },
  "series": [
    {
      "data": [120, 200, 150, 80, 70, 110, 130],
      "type": "bar",
      "showBackground": true,
      "backgroundStyle": {
        "color": "rgba(180, 180, 180, 0.2)"
      }
    }
  ]
}
```

For a more complex interactive ECharts chart, you can use the following code to test it:

Code 

```echarts
{
    "title": {
        "textStyle": {
            "align": "center",
            "color": "#fff",
