Label outside arc (Pie chart) d3.js

I\'m new to d3.js and I\"m trying to make a Pie-chart with it. I have only one problem: I can\'t get my labels outside my arcs... The labels are positioned with arc.centroid

Answer 1

yes baby, it's SOHCAHTOA

function coordinates_on_circle(hyp, angle){
  var radian= angle * Math.PI / 180 //trig uses radians
  return {
    x: Math.cos(radian) * hyp, //adj = cos(r) * hyp
    y: Math.sin(radian) * hyp //opp = sin(r) * hyp
  }
}
var radius=100
var angle=45
coordinates_on_circle(radius, angle)
