This example visualizes the relationship between horsepower and weight for a dataset of cars, displaying bars for each vehicle where the height corresponds to weight. The chart uses D3 v5 to load the auto-mpg CSV data and renders an SVG with a bar chart, using `scaleBand` for the categorical horsepower axis and `scaleLinear` for the weight axis. The code includes commented-out sections for alternative scatter plot configurations and axis labels, showing how the visualization can be adapted.
