{"version":"1.0","type":"rich","title":"Custom World Tour","description":"This example presents a custom world tour that cycles through a subset of countries in a user-defined order, rotating an orthographic globe to center each selected nation. The code uses D3 v3 with a Canvas renderer, drawing landmasses, borders, and a highlighted country via `d3.geo.path` and a `d3.geo.orthographic` projection. A queue loads TopoJSON world data and a TSV file specifying country IDs, names, and tour order. Each transition, driven by a `tween` on the projection’s rotation, animates the globe toward the next country’s centroid, updating a title label while redrawing the scene.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-c4766786fa73ae25f926d1fba57050a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
