Fork of Vega-Lite API Template
This example visualizes the relationship between engine displacement and horsepower for a collection of automobiles. It renders a scatter plot with semi-transparent points, where hovering reveals the vehicle's name via tooltip. The visualization is built using the Vega-Lite API (`vl.markPoint`, `vl.x().fieldQ`, `vl.y().fieldQ`) within a D3.js framework, with data fetched as CSV from a remote GitHub gist. Appearance is customized through a Vega config object, and rendering is handled by Vega's SVG renderer.
