{"version":"1.0","type":"rich","title":"Turtle test","description":"This stacked area chart visualizes turtle population counts for three species—Green, Loggerhead, and Hawksbill—from 1940 to 2010, based on data from `data.csv`. The chart uses `d3.stack` with `d3.stackOrderAscending` to layer the areas and `d3.area` with `d3.curveBasis` to render smooth paths in SVG. The `d3-area-label` library positions white text labels within each area, while `d3.scaleOrdinal(d3.schemeDark2)` colors the series. Hovering turns areas black, and an interactive resize listener updates the chart’s dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eb5509871dd6438a98590122e54befc6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
