A pie chart displays salary per hour for employees, with each slice colored and labeled with its dollar value, alongside a legend pairing hourly rates with time categories. The visualization uses D3 v5 APIs including `d3.csv`, `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to load data from a CSV file hosted on GitHub, compute arc paths, and assign colors. Text labels are positioned using the arc centroid method, and the chart is rendered as an SVG within a React-based HTML page.
