This pie chart visualizes the share of solar radiation for top planets, with each slice’s size proportional to its value and labeled with a percentage when above 8%. The chart is rendered as an SVG using d3.pie(), d3.arc(), and d3.scaleOrdinal with Tableau10 colors, while a legend lists each planet’s value and percentage share. Data is loaded from a remote CSV via d3.csv(). The layout uses a two-column grid for the chart and legend, with slice labels positioned via arc.centroid.
