# Third-party and provenance notices GraphFlow.studio’s browser Force Layout 2 engine was independently implemented from the published algorithm description: Mathieu Jacomy, Tommaso Venturini, Sebastien Heymann, and Mathieu Bastian, “ForceAtlas2, a Continuous Graph Layout Algorithm for Handy Network Visualization Designed for the Gephi Software,” *PLOS ONE* 9(6), 2014, . The repository contains a supplied GPL-licensed Python reference implementation under `example-impl/` for behavioral comparison. That directory and the paper copy under `doc/` are deliberately excluded from the deployable GraphFlow.studio release archive; no reference source is imported by the browser runtime. The bundled CSV datasets and MP3 soundtracks were supplied with the project. On 2026-08-28, the project owner explicitly verified and authorized those exact checksum-bound files for public release. The evidence recorded in `ASSET_PROVENANCE.json` is that project-owner authorization; it does not claim or substitute for an external license document. ## GraphFlow brand assets The same 2026-08-28 project-owner authorization covers the exact bundled GraphFlow brand mark at `assets/graphflow-mark.svg`. Its SHA-256 and approval evidence are retained in `ASSET_PROVENANCE.json`; replacing the mark reopens the fail-closed provenance gate. The 192 px and 512 px PNG install icons are deterministic rasterizations of that source mark produced by `scripts/generate_icons.py`; they do not introduce another artwork source. ## Inter Export typography uses the official Inter variable font, copyright The Inter Project Authors.
