{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map visualizes global economic data by country, with color encoding based on a scale domain. The map supports interactive filtering: users click entries in a color legend to highlight matching countries and dim all others, while a hover effect is also present. The visualization is built with D3 v5, using `d3.geoPath` and `d3.geoNaturalEarth1` for map projections. Data processing uses the `topojson` library to convert TopoJSON data for rendering. The map displays world country outlines from a world-atlas dataset, with a tooltip showing country names and values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a310389964bd4db1953edee9f08ba785?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
