-			 * Right, this is really confusing and there is a lot of maths going on here
-			 * The gist of the problem is here: https://gist.github.com/nnnick/696cc9c55f4b0beb8fe9
-			 *
-			 * 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
-			 *

+             *
+             * 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
+             *
