This scatter plot visualizes the relationship between car horsepower and weight, with each circle representing a vehicle. The chart uses D3 v5's `scaleLinear`, `axisBottom`, and `axisLeft` to map data from a CSV file of auto-mpg records onto an SVG canvas. Points are semi-transparent steelblue circles, and the visualization includes labeled axes with formatted tick marks, a title, and grid lines extending from the axis ticks.
