title: HighCharts - Make the pie chart 100% of the div
body: <p>How can I make a <code>pie</code> chart fill <code>100%</code> of the <code>div</code>it is contained in? The <code>div</code> has a width of <code>198px</code> and it's height is <code>152px</code>.</p>
  
  <p>Additionally I would like to have a <code>linear-gradient</code> effect inside each pie slice, can you advise on how to do that?</p>
