{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This visualization uses the Vega-Lite API to render an interactive scatter plot of population density data, plotting population in 2021 against density per square mile for various countries. The data is loaded from a CSV file via D3’s `csv` function, and the plot encodes country as color with tooltips showing country names. The code registers Vega, Vega-Lite, and the Vega-Lite API, applies a custom dark theme through a config object, and sizes the SVG renderer to fit the window using `autosize`. The mark-point specification sets point size and opacity, though tooltip fields are limited to the country name.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2c1f17b2933405fbde32dec1cb80f1d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
