Uncaught TypeError with a local copy of d3-v4

[abhi18av]

Hi Microsoft (@microsoft) team

I've been trying to setup VsCode for d3 dev. and everything works fine if I just use the repo example from TypeScriptSamples but I need to be able to practice them locally with d3

So, I used

curl -O https://cdnjs.cloudflare.com/ajax/libs/d3/4.4.1/d3.js

and put the file in the folder and replaced http://d3js.org/d3.v2.js with ./d3.js. But after adding the local reference the charts don't work and it raises the following error in the console

Uncaught TypeError: Cannot read property 'day' of undefined at data.ts:238

It might be an error of versioning, could you guide me how to make it work locally?

Thanks :)
