{"version":"1.0","type":"rich","title":"Project Momentum IV","description":"This choropleth map visualizes changes in forest coverage between 2000 and 2010, with a dropdown menu letting users filter by varying tree-canopy density thresholds (from 0% to 75%). Each country is colored along a red-yellow-green diverging scale (via `interpolateRdYlGn`) to indicate whether that nation gained or lost forested area at the selected threshold. The map is rendered using `d3.geoPath` and `d3.geoNaturalEarth1` projections, with country shapes loaded from a TopoJSON world atlas and forest-loss data fetched from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab7115f271004dce8f0463b03a836af9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
