Cars Scatter Plot
This scatter plot visualizes the relationship between horsepower and weight for 392 cars from the UCI Machine Learning Repository’s Auto MPG data set. Red semi-transparent circles represent individual car models, with each point positioned along linear scales created with `scaleLinear`. The chart includes labeled axes, gridlines via tick marks, and a title, all rendered as SVG using d3 v5. Data is loaded asynchronously with `csv` and parsed into numbers before being passed to a render function that appends axes and circles using d3 selections.
