This line chart visualizes bicycle sales over time, with a black path connecting data points to show the trend. The plot uses D3 scales (`scaleTime`, `scaleLinear`) for axes and a React-based rendering pipeline with SVG output. Data is loaded as CSV from a gist and parsed with `d3.csv`. Axes are generated via custom React components, while the line path is drawn using the `d3.line` generator. Styling applies Poppins font and muted teal accents.
