{"version":"1.0","type":"rich","title":"Area Chart Facebook Users","description":"This area chart visualizes Facebook’s annual user growth from 2008 to 2017, emphasizing the rising trend through a filled curve beneath a black line. Built with D3 v5, it uses `scaleLinear`, `scaleTime`, `line`, `area`, and `curveBasis` to generate smooth SVG paths, while `axisBottom` and `axisLeft` render labeled axes. Data is loaded via `csv` from a GitHub gist, with both the line and area paths appended to an SVG group. The chart highlights the dataset’s upward trajectory through the combination of stroke and fill styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/94d37015a9a643b4989656f9fe81e1d1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
