{"version":"1.0","type":"rich","title":"Fork of Untitled","description":"This example tracks the cumulative number of VizHub users since the platform’s launch on August 14, 2018. It displays a streamgraph where stacked, colored areas represent user growth over time, with a moving vertical cursor that highlights the current date. The visualization uses D3’s `d3.stack()` and `d3.area()` to construct the layered paths, while `d3.brushX()` and a custom `d3.scaleTime()` axis enable interactive time-window selection. Data is loaded from a local CSV file and rendered as an SVG with smooth transitions between brushed states.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8341e7a7676246b19a43271f11738112?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
