{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"A choropleth map colors countries by their flight data from a TSV file, with a color legend and tooltip showing total flights, trip type, and aircraft. Using D3 v5 with `geoNaturalEarth1` projection and `geoPath`, it renders the world as SVG paths from TopoJSON. The map supports zoom via `zoom` and uses `scaleOrdinal` with `schemeRdBu` for color encoding. Hover events trigger a custom tooltip div, and `colorLegend` draws circles and text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/558215f1f25e4841a631b253cc8b88cc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
