{"version":"1.0","type":"rich","title":"Locations of Datavis 2020 Students By Date","description":"A world map plots the approximate locations of students who joined Datavis 2020, with each point colored by the week they joined. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render land masses, graticules, and country borders from TopoJSON data. Student locations, manually geocoded from Slack introductions, appear as circles sized and colored by a sequential Viridis scale based on join date. A color legend with date ticks helps interpret the temporal distribution.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/19d1fcdab3104becaefbbf3a47ec07b9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
