{"version":"1.0","type":"rich","title":"Sea Turtle Survival (mock data)","description":"This stacked area chart displays the decline in sea turtle populations (Green, Loggerhead, and Hawksbill) from 1910 to 1990 using mock data. The chart uses `d3.stack` with `d3.stackOrderAscending` to layer the three species, and `d3.area` with `d3.curveBasis` for smooth paths. Labels are positioned via the `d3-area-label` library, while axes use `d3.axisBottom` and `d3.axisLeft`. The visualization renders in SVG, with hover effects that turn areas black and tooltips showing species names.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ed0d718c2c7042f5811c4e5a049c8b67?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
