title: Building a Doughnut Chart on Google API - Pie inside a Pie
body: <p>I have been trying to build a doughnut chart that is compatible with WIX. I need the chart to be somewhat interactive, at least mouse-over effects are necessary. </p>
  
  <p>Since Google API does not have doughnut charts. I made two pie charts with the goal of fitting the smaller one inside the other. I also used the pieHole option to create a hole inside each of the pies. </p>
  
  <p>After I figured out how to position two divs on top of each other I am now struggling with the problem shown in the picture. The div that contains the smaller pie is covering the div with the bigger pie. How can I make the div's background transparent while keeping the content (the smaller pie) solid? </p>
  
  <p>Any ideas are welcome. Thank you in advance!</p>
