{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"This visualization shows a world map with sized points representing nuclear explosions, where the point radius corresponds to the blast depth. The map is rendered using SVG with D3’s `geoNaturalEarth1` projection, showing graticules, land masses, and country boundaries from the World Atlas TopoJSON. City data, sourced from a CSV of nuclear explosions, is plotted as semi-transparent teal circles scaled by a `scaleSqrt` size scale based on depth values. The visualization is built with React, D3 v5 for geospatial projection and data loading, and topojson for processing world atlas shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f23c9e203556443ea58dae443cf37aba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
