Questions asking us to recommend tools can be seen as off-topic, so I suggest you rephrase your question to ask for a list of tools instead of asking for a recommendation of such tools. Even then it will be controversial.

Still, I find this topic interesting and since there is nothing wrong with your question (imo) I decided to make a search to help you out. These were my findings:

  • StackOverflow related question. This discussion has several tools worth checkign: Drawing a half gauge/speedometer (JavaScript Canvas or Java Swing Example needed)
  • UiBox. Does not use JavaSctipt, instead uses HTML5 and CSS3, so you have to be aware of the browsers you use (different browsers support different functionalities) but overall looks like a promissing and lightweight universal solution (for recent browsers, not for the likes of IE8 or related): http://www.uibox.in/item/68
  • A speedmeter implemented with JavaScript and HTML5. Has a documentation wiki with some explanations and support but imo lacks code examples: https://github.com/vjt/canvas-speedometer
  • Speedometer examples coded from scratch in codepen. No additional comments needed xD Try and enjoy! (I posted an example that I liked)

http://codepen.io/tag/speedometer/

var needle = $('needle');
var el = $('el');

var measureDeg = function() {
  // matrix-to-degree conversion from http://css-tricks.com/get-value-of-css-rotation-through-javascript/
  var st = window.getComputedStyle(needle, null);
  var tr = st.getPropertyValue("-webkit-transform") ||
           st.getPropertyValue("-moz-transform") ||
           st.getPropertyValue("-ms-transform") ||
           st.getPropertyValue("-o-transform") ||
           st.getPropertyValue("transform") ||
           "fail...";

  var values = tr.split('(')[1];
      values = values.split(')')[0];
      values = values.split(',');
  var a = values[0];
  var b = values[1];
  var c = values[2];
  var d = values[3];

  var scale = Math.sqrt(a*a + b*b);

  // arc sin, convert from radians to degrees, round
  var sin = b/scale;
  var angle = Math.round(Math.atan2(b, a) * (180/Math.PI));
  
  el.set('data-value', angle);
};

var periodicalID = measureDeg.periodical(10);
