{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This choropleth map visualizes world population data from a CSV file, displaying countries in a sequential blue color scale based on their population size. It renders an SVG with D3 v6, using `d3.geoNaturalEarth1` and `d3.geoPath` to draw country boundaries from TopoJSON world-atlas data. Interactive tooltips appear on mousemove, showing country names and population values, while a gradient legend indicates the color scale up to 1.5 billion people.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4f9a826e79c4250a7bd057c5a3b5405?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
