Stacked Bar Chart
This stacked bar chart displays the population of each U.S. state, broken down by seven age groups, with states sorted by total population. The visualization uses d3.csv to parse the data, d3.scaleBand for the x-axis, d3.scaleLinear for the y-axis, and d3.scaleOrdinal for color encoding. d3.stack computes the stacked positions, while d3.axisBottom and d3.axisLeft render the axes. The SVG rendering includes a legend and uses d3.format with SI prefixes (e.g., "10M") for population labels.
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
