This fork of a pie chart visualizes 2015 sales data for different companies using a legend and colored arcs. The chart displays each brand’s year-to-date profit converted to thousands and rendered as a simple SVG pie. The code imports D3 v5 modules like `pie`, `arc`, and `scaleOrdinal` to generate the chart, while loading data from a CSV via D3’s `csv` function. React is used as the framework, and the page is styled with custom CSS for headings and legend text.
