This example visualizes automobile data by plotting a scatterplot of weight against horsepower, with each vehicle represented by a semi-transparent red circle rendered in SVG. The chart uses D3 v5 scales, axes, and the `csv` loader to fetch and parse the auto-mpg dataset from an external URL. It applies linear scales for both variables, adds gridlines via tick sizing, and includes a title within the chart area. The visualization is built within a React and D3 framework.
