This stacked bar chart is constructed from a CSV file storing the populations of different states by age group. The chart employs conventional margins and a number of D3 features:
- d3-dsv - load and parse data
- d3-scale - x- and y-position, and color encoding
- d3-format - SI prefix formatting (e.g., “10M” for 10,000,000)
- d3-array - compute simple statistics (e.g., max)
- d3-axis - display axes
- d3-shape - computed stacked positions
