- //
- // 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
