    This stacked area chart is constructed from a TSV file storing the market share of several popular web browsers over the last year. Data is from Clicky Web Analytics. The chart employs conventional margins and a number of D3 features:

d3.tsv - load and parse data
d3.time.format - parse dates
d3.format - format percentages
d3.time.scale - x-position encoding
d3.scale.linear - y-position encoding
d3.scale.category20, a d3.scale.ordinal - color encoding
d3.extent and d3.max - compute domains
d3.layout.stack - compute stacked y-positions
d3.keys - compute column names
d3.svg.axis - display axes
d3.svg.area - display area shape
