This interactive world map visualizes the distribution of Zara and Nike shops, with each country colored according to its economy classification. Built with D3.js v5, it uses a natural Earth projection (`d3.geoNaturalEarth1`) and `d3.geoPath` to render countries from TopoJSON data loaded via `topojson.feature`. The map supports pan and zoom through `d3.zoom`, and hovering over a country changes its fill to red while a tooltip shows the country name and economy value. Color encoding uses a spectral scale from `d3.schemeSpectral`.
