{"version":"1.0","type":"rich","title":"Vega-lite test1","description":"This visualization displays the relationship between engine displacement (mpg), horsepower, weight, and country of origin for various automobile models. The data originates from the UCI Machine Learning Repository’s Auto MPG dataset. It is rendered using the Vega-Lite API, with vega-lite-api wrapping vega-lite and vega for chart generation, while d3 fetches the JSON data. The chart uses an interactive scatter plot with tooltips, circle size representing vehicle weight, and color indicating origin, with a total user session count displayed in the header.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2e000b12331e461d9a2db521d03b0458?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
