{"version":"1.0","type":"rich","title":"Choropleth Map NU","description":"A choropleth map displays the World Happiness Report 2019 scores of countries. The map uses a Robinson projection and colors each nation according to its happiness score using a sequential OrRd color scale. The visualization is built with D3 v4 and React, and renders as an SVG. The code uses `d3.geoPath`, `d3.geoRobinson`, and `d3.scaleThreshold` for the choropleth. It fetches GeoJSON and CSV data from GitHub. Interactive features include a tooltip and click-to-zoom animation using `d3.transition`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0233e40c738f443eaddee8878e920a53?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
