        Ugh, the agony. Brute force is every programmer's enemy.
        Laziness when it comes to mundane tasks is our greatest strength!

      <h2> Simple bar chart using D3 </h2>
      <p>
        Let's build an identical chart using D3!
      </p>
      <svg id="svg2">
      </svg>
      <p>
        What happens when we change our data and put a large number (say 100)
        in our data? Our bar chart fails!!
        Can we make our chart smarter by using D3 to scale our axis?
      </p>

      var barHeight = 20;

      // Simple bar chart

      // Chart with smart axis
