{"version":"1.0","type":"rich","title":"Area chart","description":"This area chart displays Facebook’s annual user growth from 2008 to 2017, using a smooth curved line and a filled area beneath it to emphasize the rising trend. The visualization loads CSV data via `d3.csv`, applies `d3.scaleLinear` for both axes, and renders axes with `d3.axisLeft` and `d3.axisBottom`. The line and area paths are generated using `d3.line` and `d3.area` with `d3.curveBasis`, while styled grid ticks and labels appear in green and orange. The SVG output includes custom tick formatting with `d3.format`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b2033041b9214850956f8b56a86c8932?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
