38	+ </p>
39	+ <p>
40	+ Instead of an ordinary video ad, vi ads are so effective because they wrap an ad with additional useful video content
41	+ that <strong>automatically matches your site's topics and attract your visitors' attention. </strong>
42	+ It's like free related content that you're paid to embed. Plus, you'll get <strong>increased visitor time-on-site and high CPMs from vi.</strong>

12986	+ *
12987	+ * Solution:
12988	+ *
12989	+ * We assume the radius of the polygon is half the size of the canvas at first
12990	+ * at each index we check if the text overlaps.
12991	+ *
12992	+ * Where it does, we store that angle and that index.
12993	+ *
12994	+ * After finding the largest index and angle we calculate how much we need to remove
12995	+ * from the shape radius to move the point inwards by that x.
12996	+ *
12997	+ * We average the left and right distances to get the maximum shape radius that can fit in the box
12998	+ * along with labels.
12999	+ *
13000	+ * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
13001	+ * on each side, removing that from the size, halving it and adding the left x protrusion width.
13002	+ *
13003	+ * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
13004	+ * and position it in the most space efficient manner

12984	+ *
12985	+ * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
12986	+ *
12987	+ * Solution:
12988	+ *
12989	+ * We assume the radius of the polygon is half the size of the canvas at first
12990	+ * at each index we check if the text overlaps.
12991	+ *
12992	+ * Where it does, we store that angle and that index.
12993	+ *
12994	+ * After finding the largest index and angle we calculate how much we need to remove
12995	+ * from the shape radius to move the point inwards by that x.
12996	+ *
12997	+ * We average the left and right distances to get the maximum shape radius that can fit in the box
12998	+ * along with labels.
12999	+ *
13000	+ * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
13001	+ * on each side, removing that from the size, halving it and adding the left x protrusion width.
13002	+ *
13003	+ * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
13004	+ * and position it in the most space efficient manner
13005	+ *
