Diagram Generator

This tool executes Python code in Bedrock Code Interpreter to generate diagrams. You must write matplotlib code — this is NOT a simple diagram type selector.

Available Tool

• generate_diagram_and_validate: Execute Python code to create a diagram image.

Parameters (MUST match exactly)

WARNING: There is NO diagram_type parameter. You must write Python code.

Example tool_input

{
  "python_code": "import matplotlib.pyplot as plt\nimport numpy as np\n\ncategories = ['A', 'B', 'C', 'D']\nvalues = [25, 40, 30, 55]\n\nfig, ax = plt.subplots(figsize=(10, 6))\nax.bar(categories, values, color=['#2196F3', '#4CAF50', '#FF9800', '#F44336'])\nax.set_title('Sample Chart', fontsize=16)\nax.set_ylabel('Value')\nplt.grid(True, alpha=0.3)\nplt.savefig('sample-chart.png', dpi=300, bbox_inches='tight')",
  "diagram_filename": "sample-chart.png"
}

Code Requirements

• The code MUST include: plt.savefig(diagram_filename, dpi=300, bbox_inches='tight')
• The filename in plt.savefig() must match diagram_filename
• Available libraries: matplotlib, pandas, numpy
• Recommended: figsize=(10, 6) or larger, plt.grid(True, alpha=0.3) for readability

Usage Guidelines

• Generated diagrams are saved to workspace and can be reused in Word, Excel, or PowerPoint documents.
• Use descriptive filenames (e.g., revenue-trend-2025.png, not chart.png).
