{"version":"1.0","type":"rich","title":"AreaChart_Task9","description":"This area chart depicts the population of China from 1950 to 2020, using a smooth, curved line to trace the trend over time and a filled orange area beneath it to emphasize the magnitude. The chart is rendered as an SVG using D3.js v5, with data loaded from a remote CSV file via `d3.csv`. Axes are generated with `d3.axisLeft` and `d3.axisBottom`, while the line and area paths are created using `d3.line` and `d3.area` with a basis curve for smoothing. Axis labels are styled via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/36acb765c5b84174be5675d6871bb14d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
