Getting error when trying to create object in custom widget.

Hi All,

I am using d3pie.js in my custom widget. I have declared the d3pie as well as d3 js files and then trying to generate a chart by creating new object using constructor in my

_updateRendering function. It is showing me that d3pie is not a constructor. So, please help me how to solve this.

Thanks.

Regards
