This visualization uses D3 v5 to create a scatter plot of cars, showing the relationship between horsepower on the x-axis and weight on the y-axis. Each circle represents a car from the auto-mpg dataset, with semi-transparent pink markers revealing density. The chart includes labeled axes with custom tick formatting and a title. D3’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` functions handle scaling and axis generation, while data is loaded via `d3.csv` and rendered as SVG circles.
