This scatter plot visualizes the relationship between car horsepower and weight, using data from the built-in `data.csv` file. Each circle represents a car model, with the axes labeled as "No. of countries" and "GDP," though these labels appear mismatched with the plotted data. The visualization uses D3 v5's `scaleLinear`, `axisLeft`, and `axisBottom` APIs to render the axes and grid lines. The SVG-based chart applies a red, semi-transparent fill to all circles and includes a title, with styling defined in `styles.css`.
