AI Agent with charts capabilities using OpenAI Structured Output

## Workflow: AI Agent with charts capabilities using OpenAI Structured Output

**Overview**
- This workflow is a experiment to integrate charts into an AI Agent
- The AI Agent has normal AI conversation and can invoke a tool to integrate a graph in the conversation.
- It uses OpenAI Structured Output to generate a chart definition according to Quickchart specifications.


**How it works**
- Activate the workflow
- Start chatting with the AI Agent.
- When the AI Agent detects that the user needs a chat, it calls the tool
- The tool calls the sub-workflow with a query.
- The sub-workflow calls the HTTP Request node (calling OpenAI) to retrieve a chart definition
- In the "set response" node, he chat definition is added at the end of a quickchart.io url - the URL to the chart image. It is sent back to the AI Agent.
- The AI Agent uses this image in its response.
- For example, you can ask the AI Agent to generate a chart about the top 5 movies at the box office


**Notes**
- The full Quickchart.io specifications have not been integrated, thus there are some possible glitches (e.g due to the size of the graph, radar graphs are not displayed properly)
- This could be provided to any automation, not only AI Agents.
