This scatterplot shows the relationship between horsepower and weight for a dataset of cars, with each circle representing a vehicle. The visualization uses a linear scale for both axes and includes labeled axis ticks, gridlines, and a title. Built with D3 v7, the code loads CSV data from an external URL and renders SVG circles, leveraging `d3.csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`. Styling applies custom colors to tick marks, labels, and the title via CSS.
