  		 *
  		 * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
  		 *
  		 * Solution:
  		 *
  		 * We assume the radius of the polygon is half the size of the canvas at first
  		 * at each index we check if the text overlaps.
  		 *
  		 * Where it does, we store that angle and that index.
  		 *
  		 * After finding the largest index and angle we calculate how much we need to remove
  		 * from the shape radius to move the point inwards by that x.
  		 *
  		 * We average the left and right distances to get the maximum shape radius that can fit in the box
  		 * along with labels.
  		 *
  		 * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
  		 * on each side, removing that from the size, halving it and adding the left x protrusion width.
  		 *
  		 * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
  		 * and position it in the most space efficient manner
  		 *
