Mermaid Diagram Generation (mermaid.ipynb)

Convert GraphContext objects to Mermaid.js diagram strings for visualization

Import

from cjm_graph_plugin_system.utils.mermaid import (
    context_to_mermaid
)

Functions

def context_to_mermaid(
    ctx: GraphContext,  # The GraphContext to visualize
    direction: str = "TD",  # Diagram direction: "TD" (top-down) or "LR" (left-right)
    node_color_map: Optional[Dict[str, str]] = None  # Map of node labels to CSS colors
) -> str:  # Mermaid.js diagram string
    "Convert a GraphContext into a Mermaid.js diagram string."

Graph Plugin Interface (plugin_interface.ipynb)

Domain-specific plugin interface for Context Graphs
