{"version":"1.0","type":"rich","title":"Global Tons of CO2 Emissions Per Year V3","description":"This choropleth map displays annual CO2 emissions per country from 1850 to 2023, colored on a green-to-red gradient with a legend, year slider, and hover highlighting for specific country values. The visualization uses React state to manage selected years and moused-over countries, while D3’s `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` render the world map. A D3 `sliderBottom` control adjusts the year, triggering color updates derived from the country’s emission value relative to the global min/max range.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ee49c2f77094e8ca7cbe31f81377f02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
