Cars Scatter Plot
This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG data set, with each red semi-transparent circle representing a vehicle. The code uses D3 v5 API functions like `select`, `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to create an SVG rendering. It employs a linear scale for both axes and includes labeled axes, a title, and a grid formed by tick lines. Data is loaded asynchronously from a remote CSV file and parsed into numeric values before being plotted.
