1813
- *
1814
- * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
1815
- *
1816
- * Solution:
1817
- *
1818
- * We assume the radius of the polygon is half the size of the canvas at first
1819
- * at each index we check if the text overlaps.
1820
- *
1821
- * Where it does, we store that angle and that index.
1822
- *
1823
- * After finding the largest index and angle we calculate how much we need to remove
1824
- * from the shape radius to move the point inwards by that x.
1825
- *
1826
- * We average the left and right distances to get the maximum shape radius that can fit in the box
1827
- * along with labels.
1828
- *
1829
- * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
1830
- * on each side, removing that from the size, halving it and adding the left x protrusion width.
1831
- *
1832
- * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
1833
- * and position it in the most space efficient manner
