This bubble chart shows the correlation between engine displacement, horsepower, and top speed for a dataset of motorcycles, with each bubble's area encoding top speed and its color representing the brand. Built with D3 v7, the visualization maps engine displacement to the x-axis and horsepower to the y-axis, using linear scales for both. It renders as an SVG, with tooltips displaying detailed specifications on hover. The color scale uses `d3.scaleOrdinal` with the `schemeCategory10` palette, and the chart is generated from a CSV file.
