This example visualizes the top five car companies and their market percentages as an interactive pie chart. Each slice displays its percentage value, with a legend showing company names alongside their corresponding percentages and color swatches. The visualization uses D3 v5 APIs including `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate the chart, and loads its data from a CSV file hosted on a GitHub gist. SVG is used for rendering all chart elements and text.
