{"version":"1.0","type":"rich","title":"\"The Human Timeline: Key Events in Climate History\"","description":"This visualization overlays three climate indicators—CO₂ levels, temperature anomaly, and sea level rise—on a shared timeline from 1993 to 2021, using d3.line to draw normalized paths. Red dashed annotations mark the Kyoto Protocol, Paris Agreement, and COP26. An animated stroke-dashoffset transition draws each line sequentially upon load, while a tooltip with d3.bisector and d3.pointer reveals exact values on hover. Data comes from merged_climate_data.csv, rendered as SVG with D3 v7 scales and axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/311bdb67ed764c4c8235d6735d50449b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
