{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart displays world population growth over time, using a filled path to emphasize the magnitude of change. The chart encodes years on the x-axis and population on the y-axis, with a title and labeled axes. Built with D3 v5, it uses `d3.scaleTime`, `d3.scaleLinear`, `d3.area` with `curveBasis`, and `d3.axisBottom`/`d3.axisLeft` for the grid and ticks. Population values are formatted as billions, and the data comes from a CSV file loaded via `d3.csv`. The visualization is rendered as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8544e1a9c0e7434daf1d20802d6b8eac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
