{"version":"1.0","type":"rich","title":"Fork of Area_Chart_facebook_users_anually","description":"This visualization shows Facebook’s annual user counts from 2008 to 2017 as a combined line and area chart. A dark line traces the growth trend while a pink filled area beneath it emphasizes the cumulative scale. The chart uses D3 v5’s `line()` and `area()` generators with a `curveBasis` interpolation, alongside `scaleLinear` for both axes. Data is loaded from a remote CSV via `d3.csv`, and the SVG rendering includes custom axis labels, tick formatting, and colored gridlines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2195a01bea5c416d8b4f7e6d00d6b1d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
