This scatterplot visualizes the relationship between car weight and miles per gallon (MPG) for vehicles from the UCI Auto MPG dataset. Each circle represents a car, with weight plotted on the x-axis and MPG on the y-axis, revealing a negative correlation. The visualization uses D3 v5’s `scaleLinear`, `axisLeft`, and `axisBottom` to construct the axes, while data is loaded via `csv` and rendered as SVG circles with gridlines. Axis labels and a title are added using D3 selections.
