title: geographic chart by nation
body: <p>I need to implement a chart like geographic chart which is an image of America seperated by state by state. And then, based on data for each state, it will the chart will display state by color.
  For example we have </p>
  
  <pre><code>California : 20 products
  Texas: 100 products
  Ohio: 5 products
  .....
  </code></pre>
  
  <p>If the number of product for a state > 20, then display that state with GREEN color, or else, display it with RED color</p>
  
  <p>Until now I have no ideas how to do it.
  I intend to split the America Map into 50 divs and color it, but it is not effective.</p>
