This scatter plot visualizes the relationship between vehicle horsepower and weight, using a red, semi-transparent circle for each car. The data comes from a CSV file about vehicle specifications. The visualization is built with D3 version 5, using `scaleLinear` for axes, `axisBottom` and `axisLeft` for tick marks, and SVG circles for data points. Axis labels and a title are added as text elements, with grid lines drawn via tick sizing, all rendered in an SVG canvas with custom CSS styling.
