Week 4: Bar Chart

README.md

Week 4: Bar Chart

Reading the data in with D3 and appending rectangles to the SVG to create a basic bar chart. This is my first bar chart.

Create a SVG:

var svg = d3.select("body")
						.append("svg")
						.attr("width", width)
						.attr("height", height);

Sort the data

data.sort(function(a, b) {
					return d3.descending(+a.year2013, +b.year2013);
					//the plus sign casts strings into numbers.
				});

Set up the domain.

var widthScale = d3.scale.linear()
					.range([ 0, width ]);

// the domain is the maximum mortality rate in 2013

widthScale.domain([ 0, d3.max(data, function(d) {
		return +d.year2013;
	}) ]);

Create rectangles and attach data

var rects = svg.selectAll("rect")
		.data(data)
		.enter()
		.append("rect");

rects.attr("x", 0)
	.attr("fill", "#0099FF")
	.attr("y", function(d, i) {
		return i * 20;   // just spacing the bars - notice from the top
	})
	.attr("width", function(d) {
		return widthScale(d.year2013);
	})
	.attr("height", 10)
	.append("title")  // this is a simple (bad) tooltip
	.text(function(d) {
		return d.name + "'s Maternal Mortality rate: " + d.year2013;
	});
