<h1>Changing Woodshop Production Goals</h1>

<p>How I want to shift my woodworking away from <strong style="color: red;">Furniture</strong> and onto <strong style="color: steelblue;">Boxes</strong> and <strong style="color: brown;">Other</strong> items over the coming years</p>

//Dimensions and padding

			var h = 600;
			var padding = [ 20, 10, 50, 100 ];  //Top, right, bottom, left

//Set up date formatting and years
			var dateFormat = d3.time.format("%Y");

//Set up scales
			var xScale = d3.time.scale()
								.range([ padding[3], w - padding[1] - padding[3] ]);
			
			var yScale = d3.scale.linear()
								.range([ padding[0], h - padding[2] ]);

//Configure axis generators
			var xAxis = d3.svg.axis()
							.scale(xScale)
							.orient("bottom")

							.tickFormat(function(d) {
								return dateFormat(d);

							.scale(yScale)
