+# ArxiGraph Viewer 
+
+This is a minimal static webapp for HuggingFace **Space** that visualizes document graphs exported by `arxitex.tools.export_hf_dataset`.
+
+The app:
+
+- Lets you enter an arXiv ID (e.g. `1706.04702` or `1706.04702v1`)
+- Only displays a graph if the corresponding JSON is present on HuggingFace
+- Visualizes the graph with a force-directed layout using D3.js
