{"version":"1.0","type":"rich","title":"Untitled","description":"A stacked area chart shows the changing levels of three turtle species—Green, Loggerhead, and Hawksbill—from 1901 to 2000, revealing a dramatic decline in all populations. The chart uses d3.area to render the stacked layers, with d3.scaleOrdinal and d3.schemeSet2 providing the color palette. Brushing, implemented via d3.brushX, allows zooming on the x-axis, while hovering highlights individual series by adjusting opacity. The d3-axis components handle the time-based and numeric scales, and the rendering is done with SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/966f537c69994bde9df63448b0f9d273?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
