{"version":"1.0","type":"rich","title":"Area Chart","description":"This area chart visualizes life expectancy in the United States over time, using a smooth, filled curve to show the trend. The D3 code (v5) loads data from a CSV file and uses `scaleTime` and `scaleLinear` for the axes, `area` with `curveBasis` to generate the smooth area path, and `axisBottom` and `axisLeft` for gridlines and labels. The title and axis labels are added as SVG text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89d178ac934d4d1aaa2f1fe35d8d07b9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
