This bar chart displays the top 10 car prices from a CSV file, with each bar sized according to the car’s price. The chart uses React to build the user interface and D3.js to handle data loading, scaling, and rendering. The visualization’s axes and bars are constructed using D3’s `scaleBand`, `scaleLinear`, and `max` functions, drawing elements as SVG rectangles. The data is fetched from a remote CSV URL and the chart includes grid lines and tick labels for readability.
