{"version":"1.0","type":"rich","title":"project","description":"This interactive choropleth map visualizes global population density (people per km²) across countries for the years 1980, 2000, 2010, and 2022. A dropdown menu switches between years, updating the color-coded SVG paths rendered with d3.geoPath and a Mercator projection. A sidebar displays the ten most densely populated countries, while hovering over a country reveals its name and density value via a styled tooltip. Data is loaded as CSV files and the world geometry from a GeoJSON source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d67c1fc2fdd34cd994bd896fa983f5fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
