# 🔗 VynFi Accounting Network Explorer
Interactive view of the v5.9.0 Method-A accounting network published in
[`VynFi/vynfi-journal-entries-1m`](https://huggingface.co/datasets/VynFi/vynfi-journal-entries-1m),
aggregated to **ISO 21378 Level-2** account classes (~30 nodes).
## What you can do
* **Filter** the underlying 61 656 line-level edges by business process
(P2P / O2C / R2R / H2R / A2R), `is_fraud`, `is_anomaly`,
minimum edge amount, and top-N.
* **Inspect** any class node to see total flow, fraud %, and the top
in/out class pairs.
* **Drill in** to the Level-3 sub-class breakdown
(`A.A.A — Operating Cash`, `A.A.B — Petty Cash`, …).
* **Toggle** force-directed vs hierarchical layout.
## Method A vs Cartesian
In v5.9.0 the JE-network defaults to *Method A* from Ivertowski 2024:
exactly **one edge per 2-line journal entry**, confidence = 1.0.
This avoids the Cartesian explosion (225 M edges on 1 M JEs) that the
legacy `cartesian` method produces, and gives a clean topology for
graph-ML training.
## Tech
Streamlit + `streamlit-agraph` (vis-network) · pandas/pyarrow ·
loads parquet directly from the HF dataset on cold-start, then
caches in-memory.
