This bubble chart visualizes the relationship between vehicle acceleration and fuel efficiency (MPG) across 19 car makes, with each circle’s size encoding price tier (high, medium, or low). It uses D3.js v7 with SVG rendering, loading data from a CSV file. The chart maps acceleration to the x-axis and MPG to the y-axis using linear scales, while a square-root scale determines bubble radius. Axes are labeled, though tick marks are not drawn. Data is processed by converting strings to numbers and lowercasing price values before scaling.
