{"version":"1.0","type":"rich","title":"Fork of Area_Chart_facebook_users_anually","description":"This visualization shows Facebook’s annual user growth from 2008 to 2017 as a combined line and area chart, with a curved trend line and a pink filled region beneath it. The SVG chart uses D3 v5’s `scaleLinear` and `scaleTime` for axes, `line()` and `area()` generators with `curveBasis` for smoothing, and `axisBottom`/`axisLeft` to render labeled tick marks. Data is loaded via `csv` from a remote GitHub gist, and axis labels are styled with custom CSS classes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3cf007d4b514d6282e37a4e893044e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
