This bubble chart visualizes the correlation between a motorcycle's average engine power, torque, and fuel consumption for a variety of brands. Each circle’s position encodes its power and torque along the x and y axes, while its size represents fuel consumption, and its color identifies the brand. The visualization uses D3.js to render the SVG, scale the data, and add interactive tooltips that display the brand on hover. A legend clarifies the size mapping, and a custom color scale based on `d3.interpolateTurbo` differentiates the manufacturers.
