{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart shows world population growth by year, using a smooth filled curve to emphasize the upward trend. It loads data from a CSV and renders to SVG with D3 v6, using `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and the `area` generator with `curveBasis`. Grid lines are drawn via axis tick sizes, and population labels are formatted using the `format` function to convert billions. The chart includes a rotated y-axis label and a title, styled with CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eedcd69fd3ee49fc9def9e67797286dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
