SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires python3, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill automates the process of updating draw.io diagrams with live data, allowing for dynamic visualization of system status, metrics, and configurations.

Core Features & Use Cases

  • Data-Driven Diagrams: Automatically update element colors, labels, and styles based on external data sources.
  • Conditional Styling: Map status values (e.g., 'healthy', 'warning', 'critical') to specific colors and apply threshold-based gradients for numeric metrics.
  • Use Case: Visualize the real-time health of your microservices architecture. The diagram's colors and labels will automatically reflect the current status and latency of each service as reported by a health API.

Quick Start

Use the conditional-formatting skill to update the diagram 'architecture.drawio' with data from the URL 'https://api.example.com/health'.

FAQPage Schema
How do I update draw.io diagrams with live data from an API?▼

Conditional formatting in draw.io maps external data values like 'healthy' or 'critical' to specific colors and styles, allowing diagrams to dynamically reflect real-time system states and latency thresholds visually.

Can I visualize microservices architecture health in draw.io automatically?▼

You need Python3 installed to run the scripts that fetch external data and perform XML manipulation for updating element styles, colors, and labels in your draw.io diagrams.

Does draw.io support threshold-based gradients for numeric metrics?▼

Yes, draw.io can support threshold-based gradients for numeric metrics by utilizing Python scripts to process external data sources and apply conditional styling rules directly to the diagram elements.

What is the best way to automate draw.io diagram styling based on system status?▼

The best way to automate draw.io diagram styling is by using Python scripts to fetch system status data and apply conditional formatting rules to update element colors, labels, and styles dynamically.
