This interactive scatter plot visualizes the relationship between horsepower and weight for various car models, with point size mapped to acceleration rate. Built with D3.js v5 and rendered as SVG, the visualization employs linear scales for both axes and encodes acceleration through a radius transformation. Hovering over any data point reveals its acceleration value via a custom tooltip. The plot includes gridlines, axis labels, and a title, with data sourced from the auto-mpg dataset and loaded via CSV.
