Circular Migration Plot

A D3-based library for creating interactive circular migration plots (chord diagrams) for the web, inspired by global-migration.info and german-migration.info. Version 1.2.0 (stable, last release ca. 2014) provides CLI tools for data filtration and compilation of CSV migration flows into JSON, plus a browser-based visualization component. Key differentiators: bundled CLI workflow for data preprocessing, minimal setup via global npm install, and dependency on D3 for rendering. The library is in maintenance mode with no recent updates.
