This scatter plot visualizes the relationship between horsepower and weight using a dataset of car names loaded from a CSV file. The chart renders as an SVG with D3.js v7, mapping horsepower to the x-axis and weight to the y-axis using linear scales. Each data point is drawn as a circle with a fixed radius, and axis labels are appended to clarify the variables. The visualization employs D3's `scaleLinear`, `axisBottom`, and `axisLeft` APIs to construct the plot, with margins and dimensions set programmatically to produce a clean, reusable layout.
