{
"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 matchdiagram_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, notchart.png).
