{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart visualizes world population growth over time, using a smooth curve to highlight the upward trend. The data is loaded from a CSV file, and each year's population is mapped to vertical height. Built with D3 v5, the visualization uses `scaleTime`, `scaleLinear`, `area` with `curveBasis`, and `axisBottom`/`axisLeft` to render the SVG. The y-axis labels are formatted from billions (G) to (B), and gridlines are drawn via tick sizes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d2ba1685dd204326973891803b15092d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
