This example visualizes the relationship between vehicle type and average price, displaying aggregated price totals as horizontal bars. It shows a bar chart comparing price values across different vehicle categories. The visualization is built using React with D3 v5, specifically employing d3.csv for data loading, d3.scaleBand and d3.scaleLinear for axes scaling, and d3.axisBottom/axisLeft for axis rendering. The chart renders as an SVG with hover effects on bars, and data comes from a CSV file listing vehicle types and their corresponding prices.
