Stacked Bar Chart
This stacked bar chart displays the population of U.S. states broken down by seven age groups, with states sorted by total population and segments color-coded by age category. The visualization is rendered as an SVG using D3 v4, loading data from a CSV file via d3.csv. The code uses d3.scaleBand for the x-axis, d3.scaleLinear for the y-axis, d3.scaleOrdinal for colors, d3.stack to compute stacked positions, and d3.axisBottom and d3.axisLeft for the axes. A legend identifies each age group, and the y-axis labels use SI-prefix formatting via d3.format.
AI-generated descriptionThis 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
