This interactive bar chart displays average retail prices for car brands, with data loaded from a GitHub Gist CSV and rendered as a React component. The visualization uses D3 v5 scales (`scaleBand`, `scaleLinear`) to map brand names and price values, while `axisBottom` and `axisLeft` generate labeled axes with rotated x-axis text. Rounded blue rectangles represent individual prices, with SVG dimensions fixed at 960×500 pixels and margins defined for the chart area. React hooks (`useState`, `useEffect`, `useRef`) manage the asynchronous data loading and axis updates after the dataset arrives.
