This network visualization displays flight routes for a selected airline using a force-directed edge bundling technique to reveal patterns in the data. The SVG rendering shows circles representing airports positioned by a physics simulation, with curved paths connecting origins and destinations. The example uses d3.forceSimulation for the layout, d3.ForceEdgeBundling to group similar routes, and d3.drag for interactive node manipulation. Data is loaded from a CSV file containing airline flight information, grouped by airline ID to create separate node-link diagrams for each carrier.
