This example displays a scatter plot of car data, with each point representing a vehicle. The visualization uses a circular mark with low opacity to show the distribution of horsepower across different regions of origin, with tooltips revealing the car’s name. The chart is built using the Vega-Lite API, which programmatically defines the visualization, while D3’s `csv` method loads the dataset. The rendering is handled by Vega and Vega-Lite, with a custom tooltip handler and styling to improve readability.
