LlamaIndex: call a calculator with a local model
The complete local starter uses Ollama llama3.1 to select a multiplication tool. Its 5,635,678 answer is the guide’s illustrative output. Install the model and integrations first; the source lists an approximately 32 GB RAM prerequisite.

LlamaIndex: inspect an author’s notebook graph preview
The author’s notebook graph preview illustrates an extracted network of entities and connections, with its original yFiles interface marks. Use the native image to inspect the overall structure. Graph-building follows the separate property-graph tutorial and its data/model prerequisites.

LlamaIndex: inspect the author’s Neo4j graph view
An original Neo4j capture shows the complete entity query below and its extracted graph. Truncated labels and imperfect generated relationships make it useful for inspecting extraction quality. The underlying essay and graph database belong to the source tutorial’s separate setup.
