TeeChart for Javascript renders charts in 3D mode using WebGL and the Three.js library.
Current status of WebGL browser support: Can I use WebGL ?
Examples:
Basic minimal example
Extended example
Geo Maps in 3D
Surface 3D XYZ
Steps to create a 3D chart:
Include Three.js scripts:

     <script src="three.min.js" type="text/javascript"></script>
     <script src="helvetiker_regular.typeface.js"<>/script>

Include TeeChart scripts:

     <script src="teechart.js" type="text/javascript"></script>
     <script src="teechart-3d.js" type="text/javascript"></script>

Create a Tee.Three context, charts and series:

      // Create 3D WebGL context:
      var three  = new Tee.Three("canvas1");

      // Create Chart:
      var Chart1 = new Tee.Chart(three);

      // Add Bar series to Chart:
      Chart1.addSeries(new Tee.Bar([5,3,2,7,1]));

Add the following code:

      // Test for valid WebGL context:

      if (three.isEnabled()) {
        Chart1.draw();
        animate();
      }
      else
      {
        // Show message to user (tell WebGL is not available in this browser) :
        // (Note: This requires adding the Detector.js script, see below).
        Detector.addGetWebGLMessage();

        // Disable WebGL and use HTML5 2D Canvas instead:
        three.setEnabled(false, Chart1);
      }

      // Loop:
      function animate() {
        three.update();
        requestAnimationFrame( animate );
      }

At page body, add an HTML canvas element:

     <canvas id="canvas1" width=800 height=500></canvas>

Optional scripts:

    To detect if browser supports WebGL:
     <script src="Detector.js" type="text/javascript"></script>

    To enable mouse drag rotation and wheel zoom:
     <script src="TrackballControls.js"></script>
