Why would you?
Well, D3 had plenty of polyfills for array functions and other goodies before they actually showed up in Apps Script, but in addition to that it also plenty of useful functions for manipulating arrays that are not implemented in Apps Script, but it also has many other functions for data manipulation and math problems.
Set up
You’ll need the d3Gas library.

Then you can do this
var d3 = d3Gas.d3;
Examples
