This pie chart visualizes STEM employment counts by sector, displaying the top 10 sectors with the highest employment numbers. Each sector is represented as a colored slice with a corresponding legend that lists the sector label and its employment value. The visualization uses D3 v5 within a React framework, employing d3.pie, d3.arc, and d3.scaleOrdinal APIs to generate the SVG chart. Data is loaded from a CSV file hosted on GitHub Gist, and mouseovers log sector employment values to the console.
