This visualization shows a map of Hong Kong using D3 v5 with SVG rendering. The map displays geographic boundaries through a projection and path generator, with the region outlined against a minimal white background. The code relies on d3.geoPath to convert GeoJSON data into SVG paths, while the page layout uses a simple 960x500 pixel SVG canvas with hidden overflow. The visualization imports D3 from a CDN and structures the map using standard D3 mapping techniques, though the specific data source file is not included in the provided files.
