D3-Population-Pyramid

Interactive D3 Population Pyramid in D3 v4. You'll need only popPyramid.min.js and D3 for your own implementation. The easiest use is to include this in your header:

<script src="popPyramid.min.js"></script>

And include something like this in your body:

<script>
  // data must be in a format with age, male, and female in each object
  var exampleData = [{ age: '0-9', male: 10, female: 12 }, { age: '10-19',
  male: 14, female: 15 }, { age: '20-29', male: 15, female: 18 }, { age:
    '30-39', male: 18, female: 18 }, { age: '40-49', male: 21, female: 22 }, {
      age: '50-59', male: 19, female: 24 }, { age: '60-69', male: 15, female: 14 }, {
        age: '70-79', male: 8, female: 10 }, { age: '80-89', male: 4, female: 5 }, {
          age: '90+', male: 2, female: 3 }];

  pyramidBuilder(exampleData, '#pyramid', {height: 400, width: 500});
</script>

What's it look like?

The chart (with default css) looks something like this:
