title: chart.js Failed to create chart: can't acquire context from the given item
body: <p>I never got into node so I am pretty sure I am doing something massively wrong here since I cannot find any info at all by googling. </p>
  
  <p>I have a django site and I wanted a JS charting library, I chose chart.js. </p>
  
  <p>I installed and like the docs, but after that I am unsure of what to do so I tried to fill in the blanks and follow their guide as much as possible. Here is what my html looks like....</p>
  
  <pre><code>&lt;script src="/public/node_modules/chart.js/dist/Chart.js"&gt;&lt;/script&gt;
  
  &lt;canvas id="myChart" width="400" height="400"&gt;&lt;/canvas&gt;
  
  &lt;script&gt;    
      var ctx = document.getElementById("myChart");
      console.log(ctx);
  
      var options = {}
  
      var data = {
          labels: ["January", "February", "March", "April", "May", "June", "July"],
          datasets: [
              {
                  label: "My First dataset",
                  fill: false,
                  lineTension: 0.1,
                  backgroundColor: "rgba(75,192,192,0.4)",
                  borderColor: "rgba(75,192,192,1)",
                  borderCapStyle: 'butt',
                  borderDash: [],
                  borderDashOffset: 0.0,
                  borderJoinStyle: 'miter',
                  pointBorderColor: "rgba(75,192,192,1)",
                  pointBackgroundColor: "#fff",
                  pointBorderWidth: 1,
                  pointHoverRadius: 5,
                  pointHoverBackgroundColor: "rgba(75,192,192,1)",
                  pointHoverBorderColor: "rgba(220,220,220,1)",
                  pointHoverBorderWidth: 2,
                  pointRadius: 1,
                  pointHitRadius: 10,
                  data: [65, 59, 80, 81, 56, 55, 40],
                  spanGaps: false,
              }
          ]
      };
  
      var myChart = new Chart({
          type: 'line',
          data: data,
          options: options
      })
  &lt;/script&gt;

  <p>I am just trying to get an example working. I put the node_modules directory that was downloaded via npm somewhere where my server would serve them up....and verified they are being served, but then I get this error when I try to build a chart. I took all the chart codes from their docs so I am pretty sure that part is right, but I can't see why I am getting this error.</p>
