This example shows a static map of the world rendered as a grid of colored squares, with each cell’s color determined by the country it overlaps. The visualization uses D3 v5 to load and parse color data from a CSV file, then maps those named colors to geographic regions defined by an embedded PNG image. The SVG pattern and image data are used to generate the final output, with no interactive elements or animations. The code relies on D3’s data-loading utilities and React for rendering the result.
