title: Exit not working properly
body: <p>Hello Im quite new to D3 and Im having trouble with exit function</p>
  
  <p>I want to make some list and bars without using SVG and everything works like a charm.</p>
  
  <p>I select the div and then append and enter my data to populate variuos divs.</p>
  
  <pre><code>var content = d3.select("#graph").selectAll("div")
          .data(bandMates)
          .enter()
          .append("div")
          .classed("member",true) //Div contenedor
  
          content
              .append("div")
              .text(function(d) { return d.name; });
  
          content
              .append("div")
              .style("height", "40px")
              .style("width", "0px")
              .style("background-color", "#ff9999")
              .transition()
              .duration(1000)
              .style("width", function (d){ return d.songs + "px";});
  
          content
              .append("div")
              .text(function(d) { return "wrote " + d.songs + " songs!"; });
  </code></pre>
  
  <p>at the end of the process I include the <code>content.exit().remove();</code> function because I want to be able to update the number of songs with another function and then calling de draw() function again.</p>
  
  <p>Firebug console is throwing me this error </p>
  
  <pre><code>content.exit is not a function
  </code></pre>
  
  <p>Am I missing something?
  I went to Bostock's tutorials and everything seems to be ok.</p>
  
  <p>I have done a JSFiddle to check out my code:</p>
