This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Each red, semi-transparent circle represents a vehicle, with positions determined by linear scales mapping those two numeric attributes. The visualization uses D3 v5 APIs such as `select`, `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`, rendering axes and circles as SVG elements. Axis labels and a title are appended as text, while tick marks and gridlines are styled via CSS.
