Visualization 1: Radar Charts (Method Capability Comparison)#

When to use: Comparing 3–8 methods across multiple dimensions; showing quality/speed/memory trade-offs; use-case recommendation.

Dimensions#

DimensionScoring Criteria (0–10)Render Quality10=SOTA, 7=competitive, 5=acceptable, 3=below baselineRender Speed10=200+ FPS, 7=60–100, 5=30–60, 3=<30Memory Efficiency10=<50MB, 7=100–500MB, 5=0.5–2GB, 3=>2GBGeometry Quality10=mesh-ready (2DGS/SuGaR), 7=decent depth, 5=approx, 3=poorScalability10=city-scale, 7=building, 5=room, 3=object-onlyEase of Use10=single script, 7=standard pipeline, 5=multi-stage, 3=complex setupNovelty10=paradigm shift, 7=significant extension, 5=incremental, 3=minor tweak

Adjust dimensions by context (compression: add "Compression Ratio"; avatar: add "Expression Fidelity"; SLAM: add "Tracking Accuracy").

Visualization 3: Method Timelines (3DGS Evolution)#

When to use: Chronological development; identifying research trends; literature review figures; conference slides.

Design Principles#

• Horizontal axis: Time (year/quarter)
• Vertical lanes: Research categories
• Node size: Significance (citation count)
• Node color: Category (use CATEGORY_COLORS, consistent with other charts)
• Connections: Show lineage (e.g., 3DGS → Scaffold-GS, 3DGS → 2DGS)

API — Static Timeline#

Workflow#

1. Identify: Visualization type (Radar/Table/Timeline), methods, output format (static/interactive/both), context (paper/presentation/comparison)
2. Gather Data: Read references/*.md for metrics; score qualitative dimensions from knowledge base; prefer user-provided data when given
3. Generate: Write Python script to .temp/; apply publication-quality styling; export PDF/PNG + HTML
4. Validate: Check readability, colorblind accessibility (Okabe-Ito), label positioning

Pre-built Presets#

• Landscape Overview: Radar + scatter + timeline combined (3 PDFs + interactive HTML)
• Category Deep Dive: Category-specific radar dimensions + detailed table + mini-timeline
• Paper Submission Package: Comparison radar (Related Work) + performance table + efficiency scatter, all at 300 DPI

Integration#

• scientific-visualization: Publication styling, journal formatting, DPI
• 3dgs-method-compare: Comparison results as data source
• 3dgs-experiment-planner: Ablation figure generation
• 3dgs-paper-reader: Extract metrics from new papers

Rules#

1. Data accuracy first: Prefer knowledge base data over estimates; mark uncertain values as "approx."
2. Color consistency: Same category-to-color mapping across all charts in one output
3. Accessibility: Okabe-Ito palette default; test grayscale readability
4. No chart junk: Remove unnecessary gridlines, 3D effects, shadows
5. Proper labeling: All axes with units; clear legends
6. Citation awareness: Include venue/year for method context
7. Interactive bonus: Always offer interactive HTML alongside static figures
