<p>By Ira Greenberg

Uses the arc() function to generate a pie chart from the data

stored in an array.</p>

<div class="learning-demo"><script type="application/processing">

size(200, 200);

int diameter = 150;

int[] angs = {30, 10, 45, 35, 60, 38, 75, 67};

for (int i=0; i<angs.length; i++){

fill(angs[i] * 3.0);

arc(width/2, height/2, diameter, diameter, lastAng, lastAng+radians(angs[i]));

lastAng += radians(angs[i]);
