{"version":"1.0","type":"rich","title":"practice16-make a map","description":"This practice builds a world map with D3.js using the Natural Earth projection via `geoNaturalEarth1` and `geoPath`, rendering country shapes as SVG paths colored by economic classification. It loads TopoJSON and TSV data from the world-atlas package, merges them with `loadAndProcessData`, and applies a sequential `scaleOrdinal` with `schemeSpectral` to map categories. A color legend is generated with `colorLegend`, and zoom interaction is enabled through `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bf1d6d578734a19a945b9c97d835fb4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
