Instead of a dull, static picture, it also reveals the divergences among the represented values on mouse hover. It returns an array with the x and y coordinate. Positive x-axis goes to the right, while the positive y-axis heads to the bottom. In order to draw the y-axis, I need to set the lowest and the highest value limit which in this case are 0 and 100. Best of all, D3 is easy to debug using the browsers built-in element inspector: the nodes that you manipulate with D3 are exactly those that the browser understands natively.
