{"version":"1.0","type":"rich","title":"D3.js v4 Mapping Tutorial 1","description":"This visualization demonstrates Kazakhstan’s administrative regions and major cities using a Mercator projection. It renders region boundaries as semi-transparent steelblue paths with hover effects, while city points scale by population using `path.pointRadius`. Regional labels appear via `d3.geoPath` centroids, with white halo text for readability. The code uses D3.js v4’s `geoMercator`, `geoPath`, and JSON loading for both the country’s GeoJSON boundaries and a separate cities dataset.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-470e031ed4b4d4e71a081d8004931f93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
