{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map displays global economic classifications by country, with an interactive color legend that filters the map by hovering or clicking on a category. The d3-scaleOrdinal and schemeSpectral color scale map each economy type to a distinct color, while d3-geoPath and geoNaturalEarth1 render the world geometry from TopoJSON data. Clicking a legend item dims non-matching countries and highlights the selected group, with zoom support via d3.zoom. The map uses SVG and d3.v5 for all rendering and interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/605acb8096f44828bae3a52777894459?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
