qgis-edge-bundling

QGIS Edge Bundling is a plugin for the QGIS Processing toolbox that implements force-directed edge bundling algorithms to visualize origin-destination flow data. It helps untangle complex networks of movement data, such as migration patterns or transportation flows, by grouping similar paths together to create clearer, more interpretable flow maps. ## Key Features - **Force-Directed Edge Bundling** — Applies physical simulation principles to bundle similar flow lines together, reducing visual clutter. - **Clustering Pre-processing** — Includes optional clustering algorithms to group origin-destination lines before bundling for improved performance. - **Flow Summarization** — Provides a summarization tool to aggregate bundled results for analysis. - **Multi-domain Examples** — Demonstrated with diverse datasets including bird migration, US migration, Vienna traffic, and flight routes. ## Philosophy The plugin is designed to make advanced flow visualization techniques accessible directly within QGIS, following academic research on effective geographic information visualization.
