I would like to insert a dimple plot into a deck.js presentation. The code below online puts the plot in the body at the background. But I would like to have the plot displayed in the section class. I think I have to change something in var svg = dimple.newSvg("body", 800, 600). Because of my very limited javascript skills I have no idea what to change exactly. Any help would be very much appreciated. 

<section class="slide" id="test-section">
 <h2>test section</h2>      
  <script type="text/javascript">
       <script src="http://d3js.org/d3.v3.min.js"></script>
       <script src="http://dimplejs.org/dist/dimple.v1.min.js"></script>
    var svg = dimple.newSvg("body", 800, 600);
    var data = [
      { "Word":"Hello", "Awesomeness":2000 },
      { "Word":"World", "Awesomeness":3000 }
    ];
    var chart = new dimple.chart(svg, data);
    chart.addCategoryAxis("x", "Word");
    chart.addMeasureAxis("y", "Awesomeness");
    chart.addSeries(null, dimple.plot.bar);
    chart.draw();
  </script>
</section>

If only the included the specific section class code in my question. If needed the complete code can be found here. The index page in the is located in the introduction folder.

A couple things need fixing:

First, you can't put a script tag inside of another script tag. You should move the code that loads d3 and dimple to the head of the document:

...
    <script src="../modernizr.custom.js"></script>  
    <script src="http://d3js.org/d3.v3.min.js"></script>
    <script src="http://dimplejs.org/dist/dimple.v1.min.js"></script>   
</head>

Second, as you suspected and John points out, something with dimple.newSvg is wrong. You probably want var svg = dimple.newSvg("#test-section", 800, 600); so the graph is only added to the test-selection slide, not all of the slides.

I would actually go one step farther and change the html a little bit so you can control precisely where the graph appears:

 <h2>Graph Title</h2>
 <div id = "graphHere"></div>  
 <h3>Some more text about the graph below the graph</h3>

To make the graph appear between the text, just change the selection passed to dimple to the id of the div we've created:

var svg = dimple.newSvg("#graphHere", 800, 600);

Finally, chart.js is doing some weird resizing the graph since it is too big to fit on the slide. Without digging through the source of chart.js, we can fix the problem by creating a smaller graph:

var svg = dimple.newSvg("#graphHere", 400, 200);

I like the look of deck.js so I just pulled it down and had a play. I then came back and found Adam had basically explained everything I just found out. You need to put a div within the slide and add the svg to that, otherwise the deck scaling code duplicates the chart.

First add a div to the relevant slide:

<section class="slide">
    <div id="myChartDiv"></div>
</section>

Then add the references to the set at the bottom (or the header if you like):

<!-- Required JS files. -->
<script src="jquery-1.7.2.min.js"></script>
<script src="core/deck.core.js"></script>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script src="http://dimplejs.org/dist/dimple.v1.min.js"></script>

then the dimple code below that:

<script type="text/javascript">

    var svg = dimple.newSvg("#myChartDiv", 800, 600);
    var data = [
      { "Word":"Hello", "Awesomeness":2000 },
      { "Word":"World", "Awesomeness":3000 }
    ];
    var chart = new dimple.chart(svg, data);
    chart.addCategoryAxis("x", "Word");
    chart.addMeasureAxis("y", "Awesomeness");
    chart.addSeries(null, dimple.plot.bar);
    chart.draw();
</script>

I hope that hopes

I've never used deck.js but have you tried:

var svg = dimple.newSvg(".slide", 800, 600);

or

var svg = dimple.newSvg("#test-section", 800, 600);

Let me know if that works. If not I'll take a look at your code.

I know that this thread is from a long time ago, but let me add one thing in addition to Adam's answer. At least on dimple v2.1.2 + deck.js v1.1.0 + Firefox 34.0, the graph is corrupted in Adam's example. It seems that the size of the div tag must be explicitly set:

<div id="graphHere" style="width:400px;height:300px;"></div> 
...
<script>
 var svg = dimple.newSvg("#graphHere", 400, 300);
 // plotting function goes here 
</script>
