Fork of Vega-Lite API Template
This example visualizes automotive data from the auto-mpg.csv dataset, plotting horsepower against year with a tooltip displaying vehicle names. The visualization is built using the Vega-Lite API, which programmatically constructs a scatter plot with semi-transparent points. The code leverages vega-lite-api, vega-lite, and vega-tooltip to render the chart as SVG, while D3.js fetches and parses the CSV data. Custom axis and label styling are applied via a shared configuration object to improve readability across the full browser window.
