This example visualizes the 148 named CSS colors as a circular fan of arcs emanating from the cursor position. As the mouse moves, the entire color wheel re-centers and re-orients around the pointer, with each arc’s fill set to its corresponding RGB hex value from the loaded CSV. Built with React and D3 v5, it uses `d3.arc` to generate the arc paths and `d3.csv` to fetch the color data, rendering everything as SVG paths within a single group translated to the current mouse coordinates.
