This example is a slight modification from Mike Bostock's bar chart example. d3Kit was used to construct the <svg> and setup all the margins.

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
