This grouped bar chart displays the population distribution across seven age groups for six U.S. states, using a distinct color for each age bracket. The chart is rendered as SVG, with bars grouped per state along the x-axis and population counts on the y-axis, formatted with SI prefixes like "10M." Built with D3 v4, the visualization loads data from a CSV file via `d3.csv`, uses `d3.scaleBand` for the x-positions and `d3.scaleLinear` for the y-axis, and applies an ordinal color scale. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and a legend is manually constructed with SVG rectangles and text.
