This pie chart visualizes COVID-19 death totals across Oceania countries and regions, with each slice labeled with the death count in thousands and accompanied by a color-coded legend listing country names and exact values. The chart renders as an SVG using d3.pie and d3.arc to generate the segments, with d3.scaleOrdinal assigning colors from a fixed palette. Data is loaded asynchronously from a CSV file via d3.csv, and the code uses d3.format to shorten large numbers for tick labels.
