This pie chart visualizes COVID-19 death statistics across seven U.S. states, with each slice labeled by state name and value. The chart uses D3.js v4’s `d3.pie` and `d3.arc` to generate SVG paths, with categorical colors via `d3.scaleOrdinal`. Hovering over a slice reduces the opacity of other slices and displays a tooltip showing the state and its corresponding death count. The visualization includes an interactive legend and is rendered entirely in SVG, with styling applied through CSS classes.
