This example displays a circular arrangement of colored arcs derived from a CSV file of named CSS colors. Each color is drawn as a small arc path, with its fill set to the corresponding RGB hex value, and its position and opacity scaled by its index in the dataset. The visualization uses React for rendering SVG elements, and D3 v7 for data loading via `d3.csv`, as well as for the `arc` generator and linear/sqrt scales that compute angular and opacity values.
