A world map displays immigrant flows between countries, with colored lines connecting origin and destination coordinates based on 2020 migration data. Clicking a country highlights it and filters the visualization to show only flows to that nation, while a horizontal bar chart at the bottom ranks the top ten destinations by immigrant count. The visualization uses React, D3 v5 APIs including `d3.geoNaturalEarth1`, `d3.geoPath`, `scaleBand`, and `scaleSqrt`, along with `d3.ForceEdgeBundling` for line bundling. Data is loaded from CSV files via D3's `csv` method, with zooming enabled through `d3.zoom`.
