title: Is it possible to load csv data to nvd3 library?
body: <p>I'm new on nvd3 after testing the D3js the last week. I'd like to <strong>load data from .csv file with nvd3</strong>, that I did on D3 but I'm not able to do it with nvd3... Someone knows how to do it? 
  With D3 I write the next lines and I get the data from my wather.csv:</p>
  
  <pre><code>d3.csv("weather.csv", function(error, data) {
      data.forEach(function(d) {
          d.date = parseDate(d.Hour);
          d.T = +d.T;
      })
  });
  </code></pre>
  
  <p>Considering my weather.csv file like:</p>
  
  <pre><code>"Hour";"T";
  "25.04.2013 12:00";"18.7";
  "25.04.2013 11:00";"18.5";
  "25.04.2013 10:00";"18.4";
  "25.04.2013 09:00";"18.9";
  ...
  </code></pre>
  
  <p>On the Nvd3 examples, I've found only variables inside the code, not loading any .csv or .json file. I'd like to load data from a file and show a simple bar chart. </p>
  
  <p><strong>UPDATED</strong></p>
  
  <p>Here I've the code that I implemented and It doesn't work. I use the function .csv from D3 but navigator says that data doesn't exist and I don't know why.</p>
  
  <pre><code>var parseDate = d3.time.format("%d.%m.%Y %H:%M").parse;
  d3.csv("weather.csv", function(error, data) {
      data.forEach(function(d) {
          d.date = parseDate(d.Hour);
          d.T = +d.T;
      })  
  
      nv.addGraph(function() {  
          //console.log(data);
          var chart = nv.models.discreteBarChart()
              .x(function(d) { return d.date })
              .y(function(d) { return d.T })
              .staggerLabels(true)
              //.staggerLabels(historicalBarChart[0].values.length &gt; 8)
              .tooltips(false)
              .showValues(true);
  
          d3.select('#chart1 svg')
              //.datum(historicalBarChart)
              .datum(data)
              .transition().duration(500)
              .call(chart);
  
          nv.utils.windowResize(chart.update);
          return chart;
      });
  });
  </code></pre>
  
  <p>Thanks.</p>
