This pie chart visualizes the distribution of job postings across different experience levels, showing the count for each category as labeled slices. The chart is rendered as an SVG using D3.js v7, with the pie layout generated by `d3.pie()` and arcs drawn via `d3.arc()`. Data is loaded from a remote CSV file using `d3.csv()`, and counts are aggregated with `d3.rollup()`. Each slice is colored with `d3.schemeCategory10` and labeled inside the arcs using centroid positioning.
