This example visualizes automobile performance data from a CSV file, plotting each car’s origin against its horsepower as a scatterplot with semi-transparent circles and tooltips showing the vehicle name. It uses the Vega-Lite API to construct the chart declaratively, with D3’s `csv` function for data loading and Vega-Tooltip for interactive hover details. The code registers Vega and Vega-Lite, then renders the visualization in an SVG view, with custom axis and label styling applied via a shared configuration object.
