+	//
+	// 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.

-	// 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

-	//
-	// 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

+	//
+	// 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
