This example renders a map of the world as a hexagonal grid using the `d3-hexgrid` library. The SVG output shows continents and country boundaries formed by hexagons, with a color scale distinguishing land from water. The visualization is built with React and uses D3’s hexbin mapping to project geographic coordinates onto hexagon cells, creating a stylized, low-resolution representation of global geography. The code initializes a 1960x800 SVG canvas and loads the hexgrid library via a CDN.
