This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. The visualization maps horsepower to the x-axis and weight to the y-axis, with red semi-transparent circles representing each car. Built with D3 v5, the code uses `csv()` to load the data, `scaleLinear()` for both axes, and `axisBottom()` and `axisLeft()` for the grid lines and labels. The rendering is done in SVG, with axis lines removed using `.remove()` and explicit text elements for the chart title and axis labels.
