{"version":"1.0","type":"rich","title":"Week 9 Make a Map","description":"This example shows an animated orthographic world map that rotates continuously while simulating day and night shading. The globe is tilted at Earth's 23.5-degree axial angle, with a dark-to-light sequential color scale marking the sunlit and shadowed hemispheres. Using d3.geoOrthographic and d3.geoPath, it renders country boundaries from the visionscarto world-atlas TopoJSON source, with d3.geoGraticule adding latitude and longitude lines. A d3.timer drives the rotation and shading updates, while a d3.scaleSequential with interpolateHcl creates the dusk-like color gradient.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c57a50fe036c4b5e8a753afab4f8ebf8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
