Stacked Bar Chart with Tooltip by D3 v4
This example shows the age distribution of the U.S. population by gender, with males and females stacked as colored segments within each age group. The chart uses D3 v4's `d3.scaleBand` for the age categories, `d3.scaleLinear` for percentages, and `d3.scaleOrdinal` for color encoding. Hovering over a segment triggers a tooltip built with a separate SVG that displays the exact value. The data comes from data.gov, and the code draws from examples by Mike Bostock and Michael Stanaland.
