A pie chart visualizes the box office collections of films starring actor Natural Star Nani, with each slice representing a film and its collection in crores. The chart uses d3.pie and d3.arc to generate the segments and d3.scaleOrdinal for color mapping. A legend lists each film with its corresponding collection value. Data is loaded asynchronously from a GitHub-hosted CSV file using d3.csv. The SVG rendering centers the chart and labels each slice with its numeric value.
