This pie chart shows the mortality rate from mental health deaths across different countries in the United States. The visualization uses D3 v5 with a standard SVG rendering approach, employing `d3.pie()` and `d3.arc()` to generate the chart segments. Each slice is colored using `d3.scaleOrdinal()`, with country names labeled directly on the segments and a legend on the right displaying country names and their corresponding death counts. The data is loaded asynchronously from a CSV file hosted on GitHub.
