{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"This example animates a map of Walmart store openings across the United States over time, using a sliding date window to reveal dots as they appear. It combines D3 v7 with a topojson map of the lower 48 states and a geographic projection via `d3.geoAlbersUsa` and `d3.geoPath`. Store locations are loaded from a TSV file and sorted by date, while a scrubber drives the animation. The code uses `d3.create`, `selection.join`, and `transition.attr` to show and hide arrival points, with a blue dot marking the current store.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/72a13ad413fb48c3982161efd5943c90?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
