{"version":"1.0","type":"rich","title":"test10","description":"This area chart displays population trends for multiple countries over time, with each country represented by a colored filled area and a corresponding legend. The visualization is built using D3.js, specifically employing `d3.scaleTime`, `d3.scaleLinear`, `d3.area`, and `d3.axisBottom`/`d3.axisLeft` for rendering. Population data is fetched from a CSV file and processed into date-value pairs, while the color scale uses `d3.scaleOrdinal` with `schemeCategory10`. The chart is rendered as an SVG with customizable dimensions and margins.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/52b71149daf043fc9d7cff6529a6d10c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
