{"version":"1.0","type":"rich","title":"Fork of Area_Chart_facebook_users_anually","description":"A combined line and area chart displays annual automobile sales in the USA from 2002 to 2018. The chart uses d3.line and d3.area with curveBasis to create a smoothed blue line over a filled aqua region, while d3.axisBottom and d3.axisLeft render labeled axes with green tick text. Data is loaded via d3.csv from a GitHub gist, parsed with unary plus operators, and rendered as SVG using d3.scaleLinear for both dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a91ab066bd4f4c47a34fd72710eef5cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
