Here is my very simple, resizable, html5 Coin Stack Gauge. It is very easy to customize so you can change it up any way you like by modifying the code.
To use this control you simply need to include a canvas object on your page and the following script at the bottom of your web page.
<canvas id='myCoins' width='100px' height='200px' ></canvas>
Put this line at the bottom of the file to include the code.
var nCoins = Math.floor(Math.random()* 20);
var nMaxCoins = 20;
Here is a link to the code ROCoinStack.js or you can pull the latest from github at https://github.com/rostafichuk/JS_Gauges.git
