{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This example displays a smoothed density estimate of the relationship between engine displacement and horsepower, with tooltips revealing car model names. Built with the vega-lite-api library, the visualization loads auto-mpg data from a CSV via d3.csv. The chart uses a filled, semi-transparent line mark to approximate a density plot, configured with custom axis and label styling. Vega-Lite handles rendering, while Vega-Tooltip provides interactive hover details.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d0c0bc3851e4529b0373c607261816e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
