Thanks for contacting Syncfusion Support.
We have analyzed your query. If you wish to render a particular control alone, then you can download that control script alone from the below link and can refer that in your sample.
In the above code, we have referred ej.chart.min.js file only which is enough to render a chart. This size will be less than 1 MB.
And we have also prepared a simple chart sample for your reference and attached in the below location.
Please let us know if you have any concern.
