This example visualizes CSS named colors as a scatterplot, showing the number of move-ins per day of the week from a CSV dataset. The chart uses React state to manage data loading and rendering, with D3 v6 functions like `scaleLinear` and `extent` to compute scales and domains. SVG circles render the aggregated data points, while custom React components handle axes and marks. The code includes formatting utilities like `format` and relies on `useEffect` and `useState` hooks for data fetching.
