This scatter plot displays the relationship between horsepower and weight for cars from the auto-mpg dataset. Each circle represents a vehicle, with horsepower plotted on the x-axis and weight on the y-axis, using D3.js version 5. The visualization uses d3.csv to load data, d3.scaleLinear for both axes, and d3.axisBottom and d3.axisLeft to render axes with grid lines. Circles are appended as SVG elements with a forest-green fill and 50% opacity. The chart includes labeled axes and a title, with margins creating space for the text elements.
