D3 4.x template by nitaku

A very simple template for using D3 4.x. D3-selection-multi is loaded to enable CoffeeScript’s shorthand notation for setting attributes:

svg.append 'circle'
  .attrs
    r: 100
    cx: width/2
    cy: height/2
    fill: 'teal'

Notice that D3 4.x uses .attrs() instead of .attr().

index.js

// Generated by CoffeeScript 1.10.0
(function() {
  var height, svg, width;

  svg = d3.select('svg');

  width = svg.node().getBoundingClientRect().width;

  height = svg.node().getBoundingClientRect().height;

  svg.append('circle').attrs({
    r: 100,
    cx: width / 2,
    cy: height / 2,
    fill: 'teal'
  });

  svg.append('circle').attrs({
    r: 60,
    cx: 2 * width / 5,
    cy: height / 3,
    fill: 'orange'
  });

}).call(this);
