{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart visualizes world population by year up to 2015, with a smooth curved line and filled region emphasizing growth trends. The SVG rendering uses D3 v5’s `scaleTime`, `scaleLinear`, and `area` generator with `curveBasis` to create the path. Axis labels and ticks are added via `axisBottom` and `axisLeft`, with population values formatted in billions. Data loads from a CSV file using D3’s `csv` method, parsing years as dates and populations as numbers before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/41f40a2f4bce4258a722b0e50293572e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
