This example presents a minimal page titled “Spatial data – 3 dec 2021,” introducing spatial data concepts through a single heading and a blue introductory paragraph. It uses D3 v7’s `d3.select` to append text to the page, styled with Google Fonts “Roboto Slab” and “Roboto” via CSS. The code demonstrates basic DOM manipulation with D3 and a static HTML structure, serving as a starting point for spatial data visualization without any maps or interactive elements.
