Custom Chart
In case if your use-case is not covered in the offered chart types, custom chart option will let you extend all the functionalities offered by the underlying package Fusion Charts. To use this on the chart widget, you'll have to select Custom Chart type in the Chart Type property. Now, you'll find a Custom Fusion Chart Configuration  property where you'll have to set the configuration of the fusion chart. 
There are almost 100+ variants of Fusion Chart Configuration, learn more from the official docs here. 
The new custom configuration requires an object with two keys, type and dataSource.
Property
Description
type
The type property takes in the type of fusion chart, you can find all the supported types  here.
dataSource
dataSource consists of customization options and the data to be mapped for your chart. It essentially has two properties chart and type.
​
 The chart object has options that are used to customize the chart for example, caption, x/y axis label etc. The data object is an array that you want to visualise, here's an example of how the data looks like :  [{"label": string, "value": string},.. ] 
Here's how the entire config should look like in the Custom Fusion Chart Configuration  property:
{{
    {
        "type": "",
        "dataSource": {
            "chart": {},
            "data": []
        }
    }
}}
Here's a quick example to create a custom Fusion Chart on Appsmith:
Building a custom Fusion Chart on Appsmith
First, drag and drop a chart widget on to the canvas.
Open the Chart's property pane by clicking on the cog icon.
Next, choose Custom Chart option under Chart Type Property. You'll now find a new property named "Custom Fusion Chart Configuration"
Now inside the Custom Fusion Chart Configuration use the moustache syntax to configure your fusion chart and add the required properties.
In this case, we'll be building a column2d chart, hence, let's use the fusion chart properties inside the config.
{{
    {
      "type":"column2d",
      "dataSource":{
          "chart":{
            
          },
          "data":[
            
          ]
      }
    }
}}
Next, add the following config to the chart and the data config:
{{
    {
      "type":"column2d",
      "dataSource":{
          "chart":{
            "caption":"Monthly revenue for last year",
            "subCaption":"Harry's SuperMart",
            "xAxisName":"Month",
            "yAxisName":"Revenues (In USD)",
            "numberPrefix":"$",
            "theme":"fusion"
          },
          "data":[
            {
                "label":"Jan",
                "value":"420000"
            },
            {
                "label":"Feb",
                "value":"810000"
            },
            {
                "label":"Mar",
                "value":"720000"
            },
            {
                "label":"Apr",
                "value":"550000"
            },
            {
                "label":"May",
                "value":"910000"
            }
          ],
          "trendlines":[
            {
                "line":[
                  {
                      "startvalue":"700000",
                      "valueOnRight":"1",
                      "displayvalue":"Monthly Target"
                  }
                ]
            }
          ]
      }
    }
}}
