{"version":"1.0","type":"rich","title":"World Population - Top 25 - Vega-Lite API Template","description":"This visualization displays the top 25 countries by population, using a circle mark to encode population size while mapping median age to color and population density to the x-axis. The chart is built with the Vega-Lite API, which constructs a specification executed by Vega, with d3.csv loading the world-population dataset. A custom configuration adjusts axis styling and label sizes, while the tooltip handler from vega-tooltip provides interactive country names. The visualization automatically fits to the browser viewport via the autosize setting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7ca85c08ab014c5abdda9e1b06186035?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
