This visualization displays all CSS named colors as a single pie chart, with each slice colored according to its corresponding RGB hex value. The data is loaded from a CSV file hosted on GitHub, and the chart is rendered as an SVG. The example demonstrates a hybrid approach combining React for component state and rendering with D3 v5 for data parsing and computing pie chart geometry, using the `d3.csv`, `d3.pie`, and `d3.arc` APIs. The code is a fork, with commented-out manual arc calculation logic as an alternative.
