{"version":"1.0","type":"rich","title":"world map","description":"This example presents a reference world map and a choropleth map showing internet users per 100 people in 2015, both rendered as SVG using D3 v7 and TopoJSON. The code employs `d3.geoNaturalEarth1` for the projection, `d3.geoPath` for generating map paths, and `d3.geoGraticule` to draw latitude and longitude lines. Country boundaries come from the world-atlas TopoJSON file, with each country colored by its rate in the second map, accompanied by a legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7ebc4bff176474dbcebf3ea10691112?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
