This is an example post with some echarts code.

```echarts
{
  "title": {
    "text": "ECharts Getting Started Example"
  },
  "responsive": true,
  "tooltip": {},
  "legend": {
    "top": "30px",
    "data": ["sales"]
  },
  "xAxis": {
    "data": ["Shirts", "Cardigans", "Chiffons", "Pants", "Heels", "Socks"]
  },
  "yAxis": {},
  "series": [
    {
      "name": "sales",
      "type": "bar",
      "data": [5, 20, 36, 10, 10, 20]
    }
  ]
}
```

Which generates:

{
  "title": {
    "text": "ECharts Getting Started Example"
  },
  "responsive": true,
  "tooltip": {},
  "legend": {
    "top": "30px",
    "data": ["sales"]
  },
  "xAxis": {
    "data": ["Shirts", "Cardigans", "Chiffons", "Pants", "Heels", "Socks"]
  },
  "yAxis": {},
  "series": [
    {
      "name": "sales",
      "type": "bar",
      "data": [5, 20, 36, 10, 10, 20]
    }
  ]
}
