This simple bar chart is constructed from a TSV file storing the frequency of letters in the English language. The chart employs conventional margins and a number of D3 features:

d3.tsv - load and parse data
d3.format - format percentages
d3.scale.ordinal - x-position encoding
d3.scale.linear - y-position encoding
d3.max - compute domains
d3.svg.axis - display axes

	function viz01() {

	w = 960;
	h = 600;

	nodeHash = new Array();

	var force = d3.layout.force()
	.gravity(.05)
	.distance(100)
