{"version":"1.0","type":"rich","title":"Final Project: Map of Nuclear Explosions","description":"This map visualizes nuclear explosions worldwide, with circle size encoding explosion magnitude and color encoding the responsible country. A linked histogram below shows the temporal distribution of events, supporting brush selection to filter the map by time period. Interactive elements include hover states on points and the color legend, click-to-inspect details, and dropdown menus filtering by purpose and deployment type. Built with React, it uses d3.geoNaturalEarth1 and d3.geoPath for map rendering, d3.scaleSqrt for sizing, d3.scaleOrdinal for color, and d3.brushX for timeline filtering. Data comes from a nuclear explosions CSV dataset, with country boundaries from World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dac8f591b5fb43558d595d344feec54a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
