{"version":"1.0","type":"rich","title":"Map of Nuclear Explosions with Time Histogram","description":"Combining a world map with a time-series histogram, this visualization plots nuclear explosions by latitude and longitude, with point size encoding yield magnitude and color indicating the responsible country. Hovering a country in the legend filters the map, while clicking a point reveals detailed deployment information. Two dropdowns filter by purpose and type of explosion. The lower histogram bins events by year using d3.bin, with counts shown on hover. Built with React, it renders SVG via d3.geoPath for the Natural Earth landmasses and d3.scaleSqrt for proportional symbol sizing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ea400705f6847d6a5d3572c6278cec8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
