{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart shows world population over time, using a filled path to emphasize the growth trend from a zero baseline. The visualization is rendered as an SVG using D3 v5, with a time-scaled x-axis and linear y-axis formatted in billions. Data is loaded from a CSV file via `d3.csv`, and the area shape is generated with the `d3.area` API using `curveBasis` for smoothing. Axis ticks and labels are styled with `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/527b7609daad452b83ab2a48a2caec1d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
