Bar Chart

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-dsv - parse tab-separated values
d3-format - number formatting
d3-scale - position encodings
d3-array - data processing
d3-axis - axes
