{"version":"1.0","type":"rich","title":"fresh block","description":"This example displays a world map with graticules and a red dot for each data point, which animates by drawing blue lines between consecutive projected coordinates in a looping sequence. A dropdown menu allows switching between Natural Earth and Aitoff projections, triggering a smooth transition via `attrTween`. The visualization uses D3 v4 with `d3.geoPath`, `d3.geoGraticule`, and TopoJSON, rendering geographic data as SVG with animated transitions.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-743bcb83eb97f74b7e636006e671a2c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
