This scatterplot is constructed from a TSV file storing the dimensions of sepals and petals of various iris flowers. The chart employs conventional margins and a number of D3 features:

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