title: Zooming using slider
body: <p>I am a beginner with jQuery and looking to build a short plugin for my requirement. I am looking to build a light and short timeline like plugin which has to look something like the following:</p>
  
  <p><img src="https://i.stack.imgur.com/n8Wu7.png" alt="enter image description here"></p>
  
  <p>The green bar below has two small rectangles which can be moved left and right towards or away from each other to zoom in / zoom out the content of the timeline above (orange bar). I tried to find similar plugin which I could use as a reference to write to zoom in/zoom out using the slider.<br/>
  I found some timeline plugins such as Timeglider etc. which have the zoom functionality  implemented in a different way and not similar to the above figure (where I could use two rectangles to zoom in/zoom out and zoom timeline in orange bar).</p>
  
  <p>I wanted to ask for suggestions about where I could find a similar plugin that I could use as a reference to see how zooming using slider is implemented. Or if there's no such already plugin, I would appreciate some help on how to go about the zooming functionaility for the plugin.</p>
