I am getting Raphael not defined error

[ymihir]

I am creating SPFx web part for SharePoint. I am trying to generate a chart using TreantJS. TreantJS using Raphael js to build the components.
I am always getting Raphael not defined error even i try with multiple ways.

1. I have loaded the script with SPComponentLoader method.
2. I have loaded with $.getScript method.
   In both ways, I have tried to print the output in console. with first method it is coming as
   with the second method it is coming as undefined.
   What is wrong here?
