{"version":"1.0","type":"rich","title":"zoom in/out, reverse triangle,tooltip country name","description":"This visualization maps global launch sites, representing the number of launches at each location with an inverted triangular marker. The marker’s height encodes the launch count via a linear scale, while the world map and graticule are rendered using d3.geoPath with a d3.geoNaturalEarth1 projection. Users can zoom and pan the SVG using d3.zoom, and hover over countries to reveal their names or over triangles to see tooltips with launch counts and location details. The map data comes from a TopoJSON world atlas, with launch data loaded via d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27c9f5ab4ddd4227a673e46a09592c48?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
