-- Improved Tooltips and tooltip callbacks for customization
-- Improved responsiveness and resizing
-- Powerful support for adding, removing, changing, and updating data on the fly
-- Animations for everything, including all elements, colors and tooltips
-- Powerful customization when you need it. Automatic and dynamic when you don't.
-- Excellent support for modern frameworks and modular build systems.
-- Even more extensible via new element controllers, core scale classes, combo chart support, and hook systems
-- Bug fixes, stability improvements, etc.

-Anything in between `<%` and `%>` will be executed as JavaScript. As in the example shown above, `<% if (label) { %>` and later `<% } %>`. Using `<%= expr %>` will print the value of the variable named by `expr` into the tooltip.
-
-The available variables to print into the tooltip depends on the chart type. In general, the following variables are available:
-
-```javascript
-{
-	value : "value of the data point",
-	label : "label for the position the data point is at",
-	datasetLabel: "label for the dataset the point is from",
-	strokeColor : "stroke color for the dataset",
-	fillColor : "fill color for the dataset",
-	highlightFill : "highlight fill color for the dataset",
-	highlightStroke : "highlight stroke color for the dataset"

+			 *
+			 * 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
