This pie chart shows the percentage of canceled hotel bookings by country, using a dataset loaded via d3.csv from a GitHub gist. It renders an SVG with a pie layout from d3.pie and d3.arc, coloring each slice with a scaleOrdinal mapping to a discrete palette. Labels display the percentage on each segment, and a legend lists countries alongside their values, all styled with CSS. The visualization relies on d3 v5, including d3.arc for concentric geometry and d3.format for axis text.
