Interactive Visualization Engine for AI-Enhanced Knowledge Graphs & Hypergraphs

OntoSight is a lightweight yet powerful Python library designed to bridge the gap between static graph visualizations and dynamic AI-driven exploration. It allows developers to create highly interactive, searchable, and "chat-ready" visualizations for complex knowledge structures with just a few lines of code.

🌟 Key Features

• Three Visualization Types:
  • Graphs (view_graph): Traditional node-edge networks for pairwise relationships
  • Hypergraphs (view_hypergraph): Multi-node relationships and complex pathways
  • Nodes (view_nodes): Pure entity collections without edges - perfect for archives, semantic spaces, and clusters
• AI-Ready Callbacks: Flexible on_search and on_chat hooks to integrate with any LLM (GPT-4, Claude, Llama 3) or Vector Database (Milvus, Pinecone, Chroma).
• Interactive Exploration: Built-in detail panels, filtering, and real-time highlighting.
• Framework Agnostic: Works with any data source. Define your schema using Pydantic and let OntoSight handle the rest.
• Developer First: Python-native API with automatic web-server management and browser launching.

🚀 Quick Start

Installation

pip install ontosight

📸 Visualization Modes

1. Standard Knowledge Graphs (view_graph)

Traditional node-edge networks for pairwise relationships. Best for social networks, dependency graphs, and classic KGs.

Main View	Intelligent Search	AI Chat

from pydantic import BaseModel
from ontosight import view_graph

class Entity(BaseModel):
    name: str
    type: str

nodes = [Entity(name="Alice", type="Person"), Entity(name="Wonderland", type="Place")]
edges = [{"source": "Alice", "target": "Wonderland", "label": "visits"}]

view_graph(
    node_list=nodes,
    edge_list=edges,
    node_id_extractor=lambda n: n.name,
    node_ids_in_edge_extractor=lambda e: (e["source"], e["target"])
)

2. Multi-Dimensional Hypergraphs (view_hypergraph)

Visualize relationships that connect more than two entities. Perfect for collaborative networks, chemical reactions, or complex logical pathways.

Main View	Intelligent Search	AI Chat

from ontosight import view_hypergraph

# A hyperedge connects multiple nodes
hyperedges = [{"id": "he1", "members": ["A", "B", "C"], "label": "Collaboration"}]

view_hypergraph(
    node_list=[{"id": "A"}, {"id": "B"}, {"id": "C"}],
    edge_list=hyperedges,
    node_id_extractor=lambda n: n["id"],
    node_ids_in_edge_extractor=lambda e: e["members"]
)

3. Entity Archives & Semantic Spaces (view_nodes)

Pure entity collections without explicit edges. Use force-clustering and semantic search to explore large-scale archives or embedding spaces.

Main View	Intelligent Search	AI Chat

from ontosight import view_nodes

recipes = [
    {"name": "Pasta", "cuisine": "Italian"},
    {"name": "Sushi", "cuisine": "Japanese"}
]

view_nodes(
    node_list=recipes,
    node_id_extractor=lambda r: r["name"],
    node_label_extractor=lambda r: r["name"]
)

🧠 AI Integration (The "Sight" in OntoSight)

OntoSight is built for the Age of AI. While it doesn't ship with a specific LLM, it provides the "plumbing" to make your graph interactive and intelligent.

Flexible Search (Vector DB Ready)

You can define a custom search callback to perform semantic search using embedding models.

def my_vector_search(query: str):
    # Logic to call your Vector DB (e.g., Milvus)
    # returns matching_nodes, matching_edges
    pass

view_graph(..., on_search=my_vector_search)

Chat

Connect a Chat interface directly to your Graph. When a user asks a question, the LLM can provide a textual answer, and OntoSight will auto-highlight the relevant subgraph.

def my_chat_handler(question: str):
    # 1. Send question to LLM (e.g., GPT-4)
    # 2. Get relevant nodes/edges from your Retrieval logic
    return "Alice is in Wonderland.", (relevant_nodes, relevant_edges)

view_graph(..., on_chat=my_chat_handler)

🛠 Advanced Features

• Schema-Driven Detail Panels: Automatically generates UI panels based on your Pydantic models.
• Hypergraph Modeling: Visualize relationships between multiple nodes simultaneously.
