neo4j-nvl-skill

neo4j-nvl-skill is a skill for Claude Code from neo4j-contrib/neo4j-skills. It costs 227 tokens per session (5,187 once invoked), scanned A, original, MIT.

A browser-based library for displaying Neo4j graph data as an interactive network of connected nodes and relationships. Neo4j is a database designed for data made up of entities and their connections.

In plain words
What is it for?
Use it to show Neo4j query results, add zooming, panning, dragging, clicking, hovering, or box selection, and embed an interactive graph in a web app.
Why use it?
It removes the need to build graph rendering and common mouse or touch interactions from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

neo4j-nvl-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 26d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 456 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to Use

  • Rendering a Neo4j graph in a browser (vanilla JS, React, Vite) with custom interactions, rendering, or data shapes
  • Visualizing driver.executeQuery results as an interactive graph
  • Wiring zoom, pan, drag, click, hover, lasso, or box-select interactions
  • Embedding NVL inside an existing app and synchronizing graph state

When NOT to Use

  • Pre-styled embedded graph view with default behavior, no custom interactions → GraphVisualization from @neo4j-ndl/react (Neo4j Needle / NDL design system) — wraps NVL with default Neo4j styling. See Use NVL or the Needle Component? below.
  • Python / Jupyter notebook graph visualization → neo4j/python-graph-visualization (the Python port of NVL)
  • Writing/optimizing Cypher → neo4j-cypher-skill
  • Driver setup / executeQuery / sessions → neo4j-driver-javascript-skill
  • Server-side data fetching with no rendering → neo4j-driver-javascript-skill
  • GDS algorithm execution → neo4j-gds-skill or neo4j-aura-graph-analytics-skill
  • GraphQL API → neo4j-graphql-skill

Use NVL or the Needle Component?

Need Use
Embed a graph view with default Neo4j styling, no custom interactions or rendering GraphVisualization from @neo4j-ndl/react (Neo4j Needle / NDL design system) — wraps NVL and accepts records shaped { id, labels, properties: { key: { stringified, type } } } (NeoNode)
Custom interactions, custom rendering, non-standard data shapes, or framework-agnostic embedding This skill — use NVL directly

If the answer is the first row, install and use the Needle component instead of NVL — do not duplicate styling work.


Install

npm install @neo4j-nvl/base                  # core (required)
npm install @neo4j-nvl/interaction-handlers  # standard interactions (optional, vanilla JS)
npm install @neo4j-nvl/react                 # React wrappers (optional)

Peer requirements: React 19 for @neo4j-nvl/react. The published peerDependency range still permits React 18, but mixing major versions is not recommended — target 19. @neo4j-nvl/layout-workers is a transitive dependency — never install directly. neo4j-driver is a peer of @neo4j-nvl/base only when using nvlResultTransformer.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
