A pie chart displays the distribution of accident rates across different countries, with each slice labeled with its percentage value. The visualization uses a legend to list countries with their corresponding values and color-coded swatches. The chart is built with D3 v5, using the `pie`, `arc`, and `scaleOrdinal` functions to generate arcs and assign colors from a custom palette. Data is loaded asynchronously from a CSV URL, and the code applies `format('.4~g')` to display tick values.
