Cars Scatter Plot
This scatter plot from the UCI Auto MPG dataset shows the relationship between horsepower and weight for cars, with each point representing a vehicle. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes, while semi-transparent red circles convey data density. Data is loaded via `csv()` from a remote URL, and the code explicitly parses numeric fields before rendering. The chart includes labeled axes and a title, with gridlines created through tick sizing.
