This bubble chart visualizes car performance by plotting horsepower on the x-axis against torque on the y-axis for various car makes. Each circle's size corresponds to the horsepower value, while its color represents the car manufacturer, with a legend identifying the makes. The visualization is rendered as an SVG using D3 v7, employing `d3.scaleLinear` for the axes, `d3.scaleSqrt` for circle radii, and `d3.scaleOrdinal` with `d3.schemeCategory10` for color encoding. Data originates from a CSV file loaded via `d3.csv`.
