This pie chart visualizes the percentage of land area per continent, with each slice colored and labeled in a static legend. The chart is rendered using SVG via D3.js (v4), where the `d3.pie()` generator and `d3.arc()` function compute the slice paths. Hovering over a slice triggers a tooltip showing the exact percentage, implemented with D3 mouse events. Data is hardcoded in the script, and the visualization includes a responsive resize handler that redraws the chart.
