Week 9: Enhancing the SustainHub GUI — Usability and Aesthetics

Following the successful integration of a basic GUI in Week 8, Week 9 focused on refining the interface to improve user experience, readability, and interactivity. The goal was to make the interface not just functional, but intuitive and visually organized.

Key Improvements

Tabbed Interface for Multi-Metric Graphs
Users can now switch between different types of visualizations (e.g., Harmony Index, RQ Trends, Load Fairness) using a clean tabbed layout.
Improved Layout and Element Grouping
Input fields, buttons, and plot previews are now better aligned and sectioned for clarity.
Inline Graph Previews (Beta)
Preliminary support for displaying output plots directly within the GUI using embedded image panels.

1. Tabbed Graph Viewer

We introduced a tab-based navigation system using ttk.Notebook, allowing users to seamlessly explore different plots generated after each simulation. This removes clutter and enhances focus on specific metrics.

Each tab currently supports:

Harmony Index recovery curves
Stress vs. Resilience Quotient (RQ) trends
Fairness and Load distribution metrics (if enabled)

2. Clean Separation of Controls and Outputs

The GUI now logically separates:

Input Section: Agent count, step count, and Run Simulation button
Output Section: Real-time status display and graph previews
Logs: Terminal-based logs retained for transparency

This refactor ensures the interface scales well as more metrics and controls are added in the coming weeks.

3. Image Embedding (Experimental)

As a first step toward real-time visualization, graphs generated post-simulation are loaded and displayed within the GUI window. While still basic, this removes the need to navigate to the data/plots/ directory manually.

4. What’s Next?

Real-time RQ and HI metric trackers during simulation steps
Theme support (dark/light mode toggle)
Option to save simulation presets for repeat testing
Embedding console logs in a scrollable widget inside the GUI

Summary

Week 9 was all about usability and polish. By enhancing the layout, organizing outputs through tabs, and embedding visualizations, SustainHub is one step closer to becoming an interactive, self-contained research tool.

Next week, we plan to focus on real-time metric previews and further unify the visual and analytical feedback loops within the GUI.

Stay tuned!
