{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart depicts global population growth from 1950 to 2015, with the area under the line filled in teal. The visualization uses D3 v5’s `area` generator with a basis curve to create the smooth filled shape, while `scaleTime` and `scaleLinear` map the year and population values. Axis labels and gridlines are rendered via `axisBottom`, `axisLeft`, and tick marks, with population formatted in billions. The data is loaded from a CSV file via `csv`, and the chart is drawn as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/49f40ac6192b483ab3c185a2e64c1517?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
