{"version":"1.0","type":"rich","title":"Vega-Lite API Template I","description":"This visualization displays automobile performance data from the UCI Auto MPG dataset, plotting horsepower against miles per gallon with each point colored by country of origin and sized by vehicle weight. Built with the Vega-Lite API, the example constructs chart specifications programmatically, encoding tooltips for car names and customizing axis styling through a config object. The implementation uses `vl.markCircle` with field encodings for quantitative and nominal data, while `getData` imports the dataset via d3's `csv` function, and the `run` function renders the visualization directly into the document body.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eb5e8f73a5b64db49235ae30f7a63fec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
