+ // 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
