This bubble chart displays the correlation between acceleration, top speed, and fuel efficiency for luxury car brands. Each circle’s position maps acceleration on the x-axis and top speed on the y-axis, while its radius encodes fuel efficiency using d3.scaleLinear. The code loads data from a CSV file and renders the SVG visualization with d3.axisBottom and d3.axisLeft. Interactive tooltips appear on mouseover events, showing each car’s specific metric values in a styled HTML div.
