{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"A world map drawn with D3.js shows country boundaries as SVG paths projected with the Natural Earth projection, with a dark sphere as the background. The visualization loads geographic data from the world-atlas TopoJSON file and renders each country as a filled path. Interactive mouseover and mouseout events change the fill color and stroke width of individual countries, providing immediate visual feedback. The code uses D3 v5 functions such as `geoPath`, `geoNaturalEarth1`, and `select` alongside the TopoJSON `feature` API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ebb201e03aaa493f99fbda61e24e3000?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
