{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This example visualizes the relationship between vehicle displacement, horsepower, weight, and model year in the classic Auto MPG dataset. A scatter plot of displacement against horsepower uses circle size to encode weight and color to distinguish model years, with hovering revealing each car’s name. Built with the Vega-Lite API, it composes marks and encodings programmatically via `vl.markCircle` and `vl.encode`, then renders through Vega and Vega-Lite with a custom tooltip handler. The data loads asynchronously from a gist CSV using d3’s `csv` function, and the chart fills the browser window with a customized dark-on-light theme.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/231ad600f61b4fbfa2417c8cb9c12c2f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
