This example demonstrates a scatterplot visualization of automobile data, plotting weight against horsepower for various car models. Each point is colored by country of origin and sized by miles per gallon. The visualization is built using the Vega-Lite API, a programmatic interface to Vega-Lite, which leverages the Vega rendering engine. The code imports data from a CSV file, configures axis styles and tooltips, and uses the vega-tooltip library to display car names on hover.
