A forked pie chart visualizes the distribution of new COVID-19 tests across geographic locations, using a D3 v5 pie layout with an SVG rendering. The chart shows the top 10 locations by test count, with each slice’s fill color and legend labels derived from the `d3.scaleOrdinal` and `d3.schemeCategory10` palette. Data is loaded from a CSV via `d3.csv`, sorted descending, and rendered with `d3.pie` and `d3.arc`; hover events log values to the console, and legends display each location’s name and test total. The React-based example is presented in an HTML page with custom CSS styling.
