This example visualizes the geographical distribution of cities from the Data Canvas Sense Your City Dataset, plotting each city as a point on a natural Earth projection of the world. The map is rendered in SVG using React, with d3.geoNaturalEarth1 and d3.geoPath drawing the sphere, graticules, landmasses, and country interiors from TopoJSON data. A supplementary scatter plot layer would likely show quantitative city attributes, though the current code only displays the spatial positions. The styling uses custom CSS classes for land, sphere, and graticule fills.
