Compilation errors when drawing a piechart using d3.js and TypeScript

Question

I am attempting to draw a pie chart using the d3.js library and TypeScript. I have the following code:

\"use strict\";
module Chart {
  export class chart {

            


        

Answer 1

Try to replace

.attr('d', arc)   

with

.attr('d', arc)  

This hides the compiler error on my computer but if that actually work... Well, I don't know.

My understanding of the problem is that you provide .data function with number values and TypeScript compiler expects that .attr will contain also a number but you provide an arc instead.
