Country Performance
This example visualizes country performance scores on an interactive world map using the Leaflet library to render the map tiles. Scored countries are marked with circular overlays positioned by latitude and longitude coordinates from the embedded dataset, with data from a `mapJson` array containing `TOTAL_SCORE`, `LATITUDE`, and `LONGITUDE` fields. The visualization shows how scores vary geographically by placing these markers over a standard Leaflet base map, with a legend and information box for reference. All map interactions, including panning and zooming, are handled by Leaflet's built-in functionality, while D3.js v5 is also loaded for potential data manipulation.
