This example displays a scatter plot of automobile data, plotting engine horsepower against model year for a dataset of vehicles. The visualization uses an SVG rendering approach, with D3 version 3’s `scaleLinear` and `d3.extent` to map the year and horsepower values to pixel coordinates. Circles represent individual data points, with axes generated via `d3.axisBottom` and `d3.axisLeft`, and the chart includes labeled axes for both variables. The code structures the plot within a reusable `scatterPlot` function, called with the dataset directly on the body element.
