Project description

MGraph AI Service Html Graph

A powerful service that transforms HTML documents into graph representations for visualization, analysis, and manipulation. Built on the MGraph AI framework.

Overview

HTML Document  ──────►  Graph Representation  ──────►  Visual Output

<html>                     ┌─────────────┐              ┌─────────────┐
  <body>           ──►     │   Nodes     │      ──►     │   DOT       │
    <div>                  │   Edges     │              │   D3        │
  </body>                  │   Clusters  │              │   Cytoscape │
</html>                    └─────────────┘              │   VisJs     │
                                                        │   Mermaid   │
                                                        │   Tree      │
                                                        └─────────────┘

The Html Graph Service converts any HTML into a multi-graph model where different aspects of the document (DOM structure, attributes, scripts, styles) are represented as interconnected graphs that can be visualized using multiple rendering engines.

Features

Feature	Description
Multi-Graph Model	5 interconnected graphs: Body, Head, Attributes, Scripts, Styles
6 Rendering Engines	DOT (Graphviz), D3, Cytoscape, VisJs, Mermaid, Tree
8 Transformations	Default, Attributes View, Full Document, Head, Scripts, Styles, and more
Round-Trip Fidelity	HTML → Graph → HTML preserves all structure including boolean attributes
Clustered Views	Group subgraphs with colored clusters for full document visualization
REST API	FastAPI-based endpoints for programmatic access
AWS Lambda Ready	Deployable as serverless function

Quick Start

Installation

pip install mgraph-ai-service-html-graph

Basic Usage

from mgraph_ai_service_html_graph.service.html_graph.Html_Graph__Export__Service import Html_Graph__Export__Service

service = Html_Graph__Export__Service()

html = """
<html>
    <body>
        <div class="container">
            <p>Hello World</p>
        </div>
    </body>
</html>
"""

# Export to DOT format
result = service.export(
    html           = html,
    engine         = 'dot',
    transformation = 'default'
)

print(result['output'])

Running the Server

# Development

# Production

API Endpoints

Export HTML to Graph

POST /api/v1/html-graph/export
Content-Type: application/json

{
    "html": "<html><body><div>Hello</div></body></html>",
    "engine": "dot",
    "transformation": "default"
}

List Available Engines

GET /api/v1/html-graph/engines

Returns: ["dot", "d3", "cytoscape", "visjs", "mermaid", "tree"]

List Available Transformations

GET /api/v1/html-graph/transformations

Returns transformation metadata including name, label, and description.

Rendering Engines

Engine	Output	Best For
DOT	Graphviz DOT → SVG	Static diagrams, documentation
D3	JSON for D3.js	Interactive web visualizations
Cytoscape	JSON for Cytoscape.js	Complex network analysis
VisJs	JSON for vis.js	Dynamic, physics-based layouts
Mermaid	Mermaid syntax	Markdown-embeddable diagrams
Tree	JSON tree structure	Hierarchical views

Transformations

Transformation	Description
`default`	Body DOM structure
`attributes-view`	Tags and their attributes
`full-document`	All 5 subgraphs with colored clusters
`head-view`	Head section structure
`scripts-view`	Script elements and content
`styles-view`	Style elements and CSS

Creating Custom Transformations

from mgraph_ai_service_html_graph.service.html_graph__transformations.Graph_Transformation__Base import Graph_Transformation__Base

class My_Custom_Transformation(Graph_Transformation__Base):

    name        : str = "my-custom"
    label       : str = "My Custom View"
    description : str = "Custom visualization"

    def html_mgraph__to__mgraph(self, html_mgraph):
        # Select which graph to visualize
        return html_mgraph.attrs_graph.mgraph

    def configure_dot(self, config):
        # Customize DOT rendering
        config.rankdir = 'LR'
        return config
