This visualization displays a scatter plot of car horsepower against weight, with acceleration mapped to the radius of each circle. The plot uses D3 v5's `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes and gridlines. A tooltip appears on mouseover, showing the car’s name, origin, and acceleration. The data is loaded from a CSV via `d3.csv` and rendered as SVG circles, with hover effects that change the circle’s fill color.
