This pie chart visualizes the market share of programming languages using D3.js v6. The visualization renders a segmented circular chart where each slice represents a language's proportional share, with distinct colors for each category. The code uses `d3.arc` and `d3.pie` to compute slice geometries, `d3.select` for DOM manipulation, and `d3.attr` to apply styling. The chart is generated entirely from a hardcoded dataset within the JavaScript file, with the rendering driven by D3's SVG path generation for each pie segment.
