{"version":"1.0","type":"rich","title":"Test","description":"This scatterplot shows the relationship between engine displacement and horsepower for a set of cars, with each point sized and colored to represent data density. The visualization fetches live data from a PHP endpoint via `d3.json` and renders it using the vega-lite-api library, which builds a Vega-Lite specification. Point opacity is set to 0.1 to reveal overlapping clusters, while tooltips display the car name using the vega-tooltip handler. The chart is configured with custom axis styling and fills the entire viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d7578099868d4cd08c75aa5b4ba7627e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
