{"version":"1.0","type":"rich","title":"Area chart","description":"This area chart displays world population trends over time, with the x-axis representing years and the y-axis showing population counts in billions. The chart uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to generate a smooth filled path, while `axisBottom` and `axisLeft` render gridlines and tick labels. Data is loaded from an external CSV file via `d3.csv`, with population values formatted using `d3.format`. The visualization includes rotated axis labels and a centered title, all rendered as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/42ef5824f11d48c6aa9f7f397eb66c66?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
