This pie chart visualizes the distribution of skills from a data science salaries dataset, showing the count of each skill as slices of a circle with a corresponding legend. The chart uses D3.js v7 to load external CSV data and applies the `d3.pie` and `d3.arc` generators to compute and draw the arcs. A color scale (`d3.scaleOrdinal` with `d3.schemeCategory10`) assigns distinct colors to each slice, while legend items are appended as SVG groups with filled rectangles and text labels. SVG is used for all rendering.
