Engimo adds support for chars rendered with help of Chart.js.

This bar chart is an example of what the support looks like:

{
    "type": "bar",
    "data": 
       {
        "labels": ["One", "Two", "Three", "Four", "Five", "Six"],
        "datasets": [{
            "label": "# of Votes",
            "data": [12, 19, 3, 5, 3, 8]
        }]
    }
}

To get chart like this one above, follow the steps:

1. Add this to the metadata section

   ---
   chart: true
   ---
   

2. Then add the chart to the page, e.g:

   ```chart
   {
       "type": "bar",
       "data": {
           "labels": ["One", "Two", "Three", "Four", "Five", "Six"],
           "datasets": [{
               "label": "# of Votes",
               "data": [12, 19, 3, 5, 3, 8]
           }]
       }
   }
   ```
   

Line charts

Line charts are also simple:

    {
    "type": "line",
        "data": {
            "labels": ["One", "Two", "Three", "Four", "Five", "Six"],
            "datasets": [
            {
                "label": "# of Votes",
                "data": [12, 19, 3, 5, 2, 3],
                "backgroundColor":"transparent",
                "borderColor":"orange"
            },
            {
                "label": "Some other set",
                "data": [15, 8, 13, 5, 5, 9],
                "backgroundColor":"transparent",
                "borderColor":"#44ccff"
            }
            ]
        }
    }

with:

```chart
    {
    "type": "line",
        "data": {
            "labels": ["One", "Two", "Three", "Four", "Five", "Six"],
            "datasets": [
            {
                "label": "# of Votes",
                "data": [12, 19, 3, 5, 2, 3],
                "backgroundColor":"transparent",
                "borderColor":"orange"
            },
            {
                "label": "Some other set",
                "data": [15, 8, 13, 5, 5, 9],
                "backgroundColor":"transparent",
                "borderColor":"#44ccff"
            }
            ]
        }
    }
```

Well, I think you get the idea.
