This visualization displays the geographic distribution of cities in Uganda on a Mercator projection map, with each city marked by a red circle. The map shows Uganda’s administrative boundaries using U.S. Atlas TopoJSON data, rendered via `d3.geoPath` and `d3.geoMercator`. City coordinates from a local CSV are plotted as circles, with zoom and pan enabled through `d3.zoom`. Tooltips appear on mouseover, though the code also includes transitions and scaling transformations for the circles.
