This scatter plot displays latitude and longitude coordinates for cities in France, the United Kingdom, and the USA, using color-coded points to distinguish countries. Built with D3 v6, the visualization uses `scaleLinear` and `extent` to map coordinates to screen positions, with `axisLeft` and `axisBottom` for axes. A legend is generated via `selectAll` with colored rectangles and text labels. The code reads hardcoded data arrays and renders points as SVG circles, with the plot filling the browser window via `window.innerWidth` and `window.innerHeight`.
