{"version":"1.0","type":"rich","title":"Vega-Lite API Template","description":"This example visualizes the relationship between engine displacement, horsepower, weight, and model year for the classic Auto MPG dataset. A scatterplot maps displacement to the x-axis and horsepower to the y-axis, with circle size encoding weight and color encoding year via Vega-Lite’s quantitative field mappings. The code uses the Vega-Lite API (`vl.markCircle`, `vl.x().fieldQ()`) to build the specification, registers it through `vega-lite-api` with vega-tooltip for interactive hover details, and loads CSV data with `d3.csv`. Styling is customized through a config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/305cbaa25719470cbcbd25e54702346a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
