{: .warning}

Use the VisualizationTool to find visualizations relevant to a question.

Step 1: Register a flow agent that will run the VisualizationTool

A flow agent runs a sequence of tools in order and returns the last tool's output. To create a flow agent, send the following register agent request:

POST /_plugins/_ml/agents/_register
{
  "name": "Test_Agent_For_Visualization_tool",
  "type": "flow",
  "description": "this is a test agent for the VisuailizationTool",
  "tools": [
      {
      "type": "VisualizationTool",
      "name": "DemoVisualizationTool",
      "parameters": {
        "index": ".kibana",
        "input": "${parameters.question}",
        "size": 3
      }
    }
  ]
}

{% include copy-curl.html %}

For parameter descriptions, see Register parameters.

OpenSearch responds with an agent ID:

{
  "agent_id": "9X7xWI0Bpc3sThaJdY9i"
}

Step 2: Run the agent

Before you run the agent, make sure that you add the sample OpenSearch Dashboards Sample eCommerce orders dataset. To learn more, see Adding sample data.

Then, run the agent by sending the following request:

POST /_plugins/_ml/agents/9X7xWI0Bpc3sThaJdY9i/_execute
{
  "parameters": {
    "question": "what's the revenue for today?"
  }
}

{% include copy-curl.html %}

By default, OpenSearch returns the top three matching visualizations. You can use the size parameter to specify the number of results returned. The output is returned in CSV format. The output includes two columns: Title (the visualization title displayed in OpenSearch Dashboards) and Id (a unique ID for this visualization):

{
  "inference_results": [
    {
      "output": [
        {
          "name": "response",
          "result": """Title,Id
[eCommerce] Total Revenue,10f1a240-b891-11e8-a6d9-e546fe2bba5f
"""
        }
      ]
    }
  ]
}
