Agent visualization allows you to generate a structured graphical representation of agents and their relationships using Graphviz. This is useful for understanding how agents, tools, and handoffs interact within an application.
Install the optional viz
dependency group:
pip install "openai-agents[viz]"
You can generate an agent visualization using the draw_graph
function. This function creates a directed graph where:
- Agents are represented as yellow boxes.
- Tools are represented as green ellipses.
- Handoffs are directed edges from one agent to another.
from agents import Agent, function_tool
from agents.extensions.visualization import draw_graph
@function_tool
def get_weather(city: str) -> str:
return f"The weather in {city} is sunny."
spanish_agent = Agent(
name="Spanish agent",
instructions="You only speak Spanish.",
)
english_agent = Agent(
name="English agent",
instructions="You only speak English",
)
triage_agent = Agent(
name="Triage agent",
instructions="Handoff to the appropriate agent based on the language of the request.",
handoffs=[spanish_agent, english_agent],
tools=[get_weather],
)
draw_graph(triage_agent)
This generates a graph that visually represents the structure of the triage agent and its connections to sub-agents and tools.
The generated graph includes:
- A start node (
__start__
) indicating the entry point. - Agents represented as rectangles with yellow fill.
- Tools represented as ellipses with green fill.
- Directed edges indicating interactions:
- Solid arrows for agent-to-agent handoffs.
- Dotted arrows for tool invocations.
- An end node (
__end__
) indicating where execution terminates.
By default, draw_graph
displays the graph inline. To show the graph in a separate window, write the following:
draw_graph(triage_agent).view()
By default, draw_graph
displays the graph inline. To save it as a file, specify a filename:
draw_graph(triage_agent, filename="agent_graph.png")
This will generate agent_graph.png
in the working directory.
