This bar chart displays the distribution of males and females across six age groups, ranging from 20 to 50 years, using a pie chart layout. Built with D3.js v7, it fetches CSV data from a GitHub gist, processes the counts by age group and gender, and renders the visualization as SVG. The chart includes a legend showing total counts per age group and uses an interactive tooltip that appears on mouseover to reveal the specific male and female counts for each slice.
