This pie chart visualizes the population distribution of Texas by six age groups, from children to senior citizens, using a legend to identify each category. It employs D3 v6’s `d3.pie` and `d3.arc` generators to compute and render the SVG arc paths, with each slice filled by a distinct color from a predefined list. The chart loads data from a CSV file via `d3.csv` and displays percentages as proportional segments, with the legend positioned alongside the chart for clear labeling.
