{"version":"1.0","type":"rich","title":"Count and Purpose of Nuclear Explosions","description":"This stacked bar chart shows the number of nuclear explosions by country, colored by purpose, revealing that the USA deployed the most devices, mostly for weapons development. The visualization uses Vega-Lite API with d3.csv to load nuclear explosion data from a GitHub Gist, encoding country on the x-axis, count on the y-axis, and purpose as color. Tooltips display the purpose field, while custom configuration adjusts axis labels and tick styling for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/951ee3e6df1446929164d6833eefc92d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
