{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This example displays world population from 1950 to 2015 as a smooth area chart, using a time-scaled x-axis and a linear y-axis. The chart is rendered with SVG, and the area path is generated using `d3.area` with `curveBasis`. Axes are created via `axisBottom` and `axisLeft`, with population values formatted in billions. Data is loaded from a CSV using `d3.csv`, with years parsed as dates and population values multiplied by 1000.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eeb6e8696db8438ba98e9fd12a8daf72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
