This visualization shows a map of England with its geographical regions highlighted in solid blue, using a Natural Earth projection to render the country’s shape. The region boundaries are drawn as thin, semi-transparent lines, clarifying internal divisions while keeping the overall outline visible. Built with React and D3 v7, it applies `geoNaturalEarth1` and `geoPath` to project and draw the features from a TopoJSON dataset, with `feature` and `mesh` from TopoJSON separating regions and interiors. The SVG rendering approach is direct, with no interaction or animation.
