{"version":"1.0","type":"rich","title":"Untitled","description":"This example presents a choropleth map of global population by country, rendered as an SVG using D3.js v4. It employs a Mercator projection via `d3.geoMercator` and draws country boundaries with `d3.geoPath`. The fill color for each nation is determined by a threshold color scale that bins population values into a blue scheme from `d3.schemeBlues`. Data is loaded asynchronously with `d3.json` for the world GeoJSON topology and `d3.csv` for population figures.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ce60480febf44ccbd2f5a304c227d05?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
