Multiple NVD3 charts on page. How to simplify the javascript code and wrap function?

I am currently using NVD3 on website to graph charts with one of the pages having 6 charts. I have currently just add 6 functions for each the six graphs but I feel that this is not the most elegant way of approaching the problem. Below is an example of the relevant html/javascript code:

<div id="chicago" class='with-3d-shadow with-transitions chart'>
  <svg> </svg>
</div>

nv.addGraph(function() {
  var chicago = nv.models.lineChart()
      .margin({top: 30, right: 60, bottom: 50, left: 80})
      .x(function(d,i) { return i })
      .color(d3.scale.category10().range());

  chicago.transitionDuration(500);

  chicago.xAxis.tickFormat(function(d) {

      var dx = testdata[0].values[d] && testdata[0].values[d].x || 0;
      if (dx > 0) {
          return d3.time.format('%x')(new Date(dx))
      }
      return null;
  });

  chicago.yAxis
      .axisLabel('Price ($/Dth)')
      .tickFormat(function(d) { return '$' + d3.format(',.2f')(d) });

  nv.log(testdata);
  d3.select('#chicago svg')
      .datum(testdata)
      .call(chicago);

  nv.utils.windowResize(chicago.update);

  return chicago;
});

How would I wrap that function so I can reuse it multiple times without have to repeat it and replace the name (in this case 'chicago') for every graph?

It's quite simple, this is one way of doing it.

HTML :

<div id='chart1'>
    <h3>My Chart 1</h3>
    <svg></svg>
</div>
<div id='chart2'>
    <h3>My Chart 2</h3>
    <svg></svg>
</div>
<div id='chart3'>
    <h3>My Chart 3</h3>
    <svg></svg>
</div>

JavaScript :

// Call my charts , pass in my div id here
drawChart('chart1');
drawChart('chart2');
drawChart('chart3');

//Donut chart example
function drawChart(div) {
    var width = height = 400;
    
    nv.addGraph(function () {
        var chart = nv.models.pieChart()
            .x(function (d) {
            return d.label
        }).y(function (d) {
            return d.value
        }).width(width)
          .height(height)
          .showLabels(true)
          .labelThreshold(.05)
          .labelType("percent")
          .donut(true);

        d3.select("#" + div + " svg")
            .datum(exampleData())
            .attr('width', width).attr('height', height)
            .transition().duration(350)
            .call(chart);

        return chart;
    });
}

Here is a working version of it.
