This interactive SVG world map visualizes country-level data from a CSV file, using a color scale from light blue to red to represent the "value" field for each country. Built with D3 v5 and the `d3.geo.orthographic` projection, it loads country geometries from a TopoJSON file and colors them via `d3.scale.linear`. Users can click on any country to explore its associated information, though the detailed interaction logic is not fully implemented in the provided code. The map renders geographic paths with `d3.geo.path` and includes a legend for the color scale.
