D3.JS code not working

So I have found this page about D3.JS but I cannot make the code shown there work...

code:

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Step 1 - A Basic Pie Chart</title> <link rel="stylesheet" href="normalize.css"> </head> <body> <div id="chart"></div> <script src="d3.v3.min.js"></script> <script> (function(d3) { 'use strict';

    var dataset = [
      { label: 'Abulia', count: 10 }, 
      { label: 'Betelgeuse', count: 20 },
      { label: 'Cantaloupe', count: 30 },
      { label: 'Dijkstra', count: 40 }
    ];

    var width = 360;
    var height = 360;
    var radius = Math.min(width, height) / 2;

    var color = d3.scale.category20b();

    var svg = d3.select('#chart')
      .append('svg')
      .attr('width', width)
      .attr('height', height)
      .append('g')
      .attr('transform', 'translate(' + (width / 2) + 
        ',' + (height / 2) + ')');

    var arc = d3.svg.arc()
      .outerRadius(radius);

    var pie = d3.layout.pie()
      .value(function(d) { return d.count; })
      .sort(null);

    var path = svg.selectAll('path')
      .data(pie(dataset))
      .enter()
      .append('path')
      .attr('d', arc)
      .attr('fill', function(d, i) { 
        return color(d.data.label);
      });

  })(window.d3);
</script>

</body> </html>
