{"version":"1.0","type":"rich","title":"Twitter Sentiment on Climate Change","description":"A choropleth-style world map displays country-level population estimates, with semi-transparent teal circles sized by population and drawn at each country’s geographic centroid via `d3.geoPath`, `geoCentroid`, and `geoNaturalEarth1`. A size legend using `scaleSqrt` and a custom `sizeLegend` component conveys population magnitudes, while a color legend from `colorLegend.js` appears unused. The map loads Twitter sentiment data from a CSV and world boundaries from TopoJSON, supporting zoom via `d3.zoom`. Countries with missing data render in a darker fill, and hovering highlights them with a teal fill.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9b2e6d45a1fa4865bfa24b6449241457?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
