This example loads geographic boundary data from the visionscarto-world-atlas dataset and logs it to the browser console, demonstrating the first step of fetching and parsing GeoJSON with d3-fetch’s `json` function. It shows a minimal HTML page with a container div, though no map is rendered yet. The code relies on D3 version 6.7.0 as a dependency, but performs no projection or drawing—the visualization remains purely data acquisition and inspection.
