This interactive bar chart displays top-selling car brands based on price data loaded from a CSV file. The visualization uses React for component structure and D3.js v7 for scaling and axis rendering. The code leverages `d3.csv`, `scaleBand`, `scaleLinear`, `axisBottom`, `axisLeft`, and SVG `rect` elements to draw bars. The chart renders in a browser with a title, showing each model's price on the y-axis and model names on the x-axis.
