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

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