Only the file name is needed since graphviz's `render()` automatically adds the file extension. Also, unnecessary .gv (.dot) files are output, so the `cleanup=True` option has been modified to prevent them from being saved. Here is a similar modification, but in a different content. - https://github.com/openai/openai-agents-python/pull/451

# Agent Visualization
|
|
|
|
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.
|
|
|
|
## Installation
|
|
|
|
Install the optional `viz` dependency group:
|
|
|
|
```bash
|
|
pip install "openai-agents[viz]"
|
|
```
|
|
|
|
## Generating a Graph
|
|
|
|
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.
|
|
|
|
### Example Usage
|
|
|
|
```python
|
|
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.
|
|
|
|
|
|
## Understanding the Visualization
|
|
|
|
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.
|
|
|
|
## Customizing the Graph
|
|
|
|
### Showing the Graph
|
|
By default, `draw_graph` displays the graph inline. To show the graph in a separate window, write the following:
|
|
|
|
```python
|
|
draw_graph(triage_agent).view()
|
|
```
|
|
|
|
### Saving the Graph
|
|
By default, `draw_graph` displays the graph inline. To save it as a file, specify a filename:
|
|
|
|
```python
|
|
draw_graph(triage_agent, filename="agent_graph")
|
|
```
|
|
|
|
This will generate `agent_graph.png` in the working directory.
