{"version":"1.0","type":"rich","title":"World Map and Pattern Transitions","description":"This example renders a world map using TopoJSON country boundaries from the world-atlas package and projects them with d3.geoMercator and d3.geoPath. Each country is filled with an SVG pattern that continuously animates: a small orange rectangle expands to cover the 20-by-20-pixel tile, then resets, alternating between orange and white fills via a recursive transition with d3.easeQuadOut. The pattern is rotated 45 degrees, creating a dynamic striped texture across all landmasses.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4f5d283cab8a4077e6831bceb65969aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
