This scatterplot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset. Each circle represents a car, with the x-axis showing horsepower and the y-axis showing weight. The chart uses D3 v5 (specifically `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom`) to map data to SVG coordinates, with styled grid lines, axis labels, and a title. The data is loaded via `csv` from a remote URL and parsed to numeric values before rendering.
