 |  |  |
|---|---|---|
| Open Excel or JSON files, explore demo networks, or take a tour; zero install with portable versions | Write expressive queries with boolean logic, nested conditions, and range operators to filter your graph | Lasso select elements, undo and redo, focus and expand neighborhoods, and group nodes visually |
 |  |  |
| Filter by any property using range sliders and dropdown checklists, inspect node and edge metadata via tooltips, and navigate large graphs with a minimap | Compute centrality metrics like degree, betweenness, closeness, eigenvector, and PageRank, and edit your graph data live in a built-in spreadsheet | Customize shapes, sizes, colors, labels, halos, badges, arrows, pie-chart nodes, animated edge flow, and bubble set appearance per element, with an optional density-heatmap overlay |
 |  |  |
| Create independent workspaces, each preserving their own node positions, styles, filters, and bubble set groups | Ask questions in plain English — the assistant translates them into filters, queries, and styling actions | Map numeric properties to continuous color gradients with configurable stops, and export graphs as JSON, PNG, SVG, or Excel |
npm install # install dependencies
npm run bundle:serve # dev server with watch + sourcemaps
npm run serve # static http-server on :8000
npm start # electron app
npm run dist-linux # Linux build
npm run dist-windows # Windows build
npm run serve:api # standalone ingest service (HTTP API + live viewer)See CONTRIBUTING.md for the full list of npm scripts, version management, code style, and commit guidelines.
Run Graph Lens Lite as a small standalone service so other apps can push graphs to it over HTTP and watch them render live in the browser:
cp .env.example .env # set GLL_API_TOKEN
npm run serve:api # serves the viewer + ingest API (default :7637)curl -X POST http://127.0.0.1:7637/api/graph \
-H "Authorization: Bearer $GLL_API_TOKEN" -H "Content-Type: application/json" \
-d '{"nodes":[{"id":"A"},{"id":"B"}],"edges":[{"source":"A","target":"B"}]}'Open http://127.0.0.1:7637/ and the pushed graph appears; further pushes update it live.
- SERVICE.md — running, configuring, and deploying the ingest service.
- API.md — payload reference for other apps: how to build JSON for meaningful graphs (styling, filterable data, bubble groups, layouts).
