{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This example visualizes the relationship between automobile fuel efficiency (mpg), vehicle weight, and horsepower, colored by country of origin, using a scatter plot of circles with tooltips. It is built with the Vega-Lite API for D3.js, which constructs a specification rendered via Vega and Vega-Lite. The visualization loads an auto-mpg CSV dataset from a GitHub gist, sets circle size and opacity via `markCircle`, and encodes fields using methods like `.fieldQ('mpg')` and `.fieldN('origin')`. The tooltip uses the `vega-tooltip` handler, and the chart resizes to fit the window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e9c71113eaef4e26bfc23fbd46d37eaf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
