title: Light weight graph and gauge library in javascript
body: <p>I am looking for a light weight <strong>chart and gauge library</strong> in java script to design web pages
  of an embedded product.</p>
  
  <p>I searched in Google but many were heavy and some libraries were needed be downloaded at run time.
  Since mine is an embedded device I need a small size js library.</p>
  
  <p>Thanks</p>
