---# PPTX Research Posters (HTML-Based)
## Overview
**⚠️ USE THIS SKILL ONLY WHEN USER EXPLICITLY REQUESTS PPTX/POWERPOINT POSTER FORMAT.**
For standard research posters, use the **latex-posters** skill instead, which provides better typographic control and is the default for academic conferences.
This skill creates research posters using HTML/CSS, which can then be exported to PDF or converted to PowerPoint format. The web-based approach offers:
- Modern, responsive layouts
- Easy integration of AI-generated visuals
- Quick iteration and preview in browser
- Export to PDF via browser print function
- User explicitly requests "PPTX poster", "PowerPoint poster", or "PPT poster"
- User specifically asks for HTML-based poster
- User needs to edit poster in PowerPoint after creation
- LaTeX is not available or user requests non-LaTeX solution
**DO NOT use this skill when:**
- User asks for a "poster" without specifying format → Use latex-posters
- User asks for "research poster" or "conference poster" → Use latex-posters
- User mentions LaTeX, tikzposter, beamerposter, or baposter → Use latex-posters
## AI-Powered Visual Element Generation
**STANDARD WORKFLOW: Generate ALL major visual elements using AI before creating the HTML poster.**
This is the recommended approach for creating visually compelling posters:
1. Plan all visual elements needed (hero image, intro, methods, results, conclusions)
2. Generate each element using scientific-schematics or Nano Banana Pro
3. Assemble generated images in the HTML template
4. Add text content around the visuals
**Target: 60-70% of poster area should be AI-generated visuals, 30-40% text.**

### CRITICAL: Poster-Size Font Requirements
**⚠️ ALL text within AI-generated visualizations MUST be poster-readable.**
When generating graphics for posters, you MUST include font size specifications in EVERY prompt. Poster graphics are viewed from 4-6 feet away, so text must be LARGE.
**MANDATORY prompt requirements for EVERY poster graphic:**
```
POSTER FORMAT REQUIREMENTS (STRICTLY ENFORCE):
- ABSOLUTE MAXIMUM 3-4 elements per graphic (3 is ideal)
- ABSOLUTE MAXIMUM 10 words total in the entire graphic
- NO complex workflows with 5+ steps (split into 2-3 simple graphics instead)
- NO multi-level nested diagrams (flatten to single level)
- NO case studies with multiple sub-sections (one key point per case)
- ALL text GIANT BOLD (80pt+ for labels, 120pt+ for key numbers)
- High contrast ONLY (dark on white OR white on dark, NO gradients with text)
- MANDATORY 50% white space minimum (half the graphic should be empty)
- Thick lines only (5px+ minimum), large icons (200px+ minimum)
- ONE SINGLE MESSAGE per graphic (not 3 related messages)
```
**⚠️ BEFORE GENERATING: Review your prompt and count elements**
- If your description has 5+ items → STOP. Split into multiple graphics
- If your workflow has 5+ stages → STOP. Show only 3-4 high-level steps
- If your comparison has 4+ methods → STOP. Show only top 3 or Our vs Best Baseline
# ✅ Same content, simplified to readable poster format
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word in GIANT bold (120pt+). Thick arrows (10px). 60% white space. ONLY these 3 words. NO substeps. Readable from 12 feet." -o figures/workflow_simple.png
```

### CRITICAL: Preventing Content Overflow
**⚠️ POSTERS MUST NOT HAVE TEXT OR CONTENT CUT OFF AT EDGES.**
**Before creating the HTML, generate all visual elements:**
```bash
# Create figures directory
mkdir -p figures
# Hero image - SIMPLE, impactful
python scripts/generate_schematic.py "POSTER FORMAT for A0. Hero banner: '[TOPIC]' in HUGE text (120pt+). Dark blue gradient background. ONE iconic visual. Minimal text. Readable from 15 feet." -o figures/hero.png
# Introduction visual - ONLY 3 elements
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 icons: [icon1] → [icon2] → [icon3]. ONE word labels (80pt+). 50% white space. Readable from 8 feet." -o figures/intro.png
# Methods flowchart - ONLY 4 steps
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: STEP1 → STEP2 → STEP3 → STEP4. GIANT labels (100pt+). Thick arrows. 50% white space. NO sub-steps." -o figures/workflow.png
# Results visualization - ONLY 3 bars
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: BASELINE (70%), EXISTING (85%), OURS (95%). GIANT percentages ON bars (120pt+). NO axis, NO legend. 50% white space." -o figures/results.png
# Conclusions - EXACTLY 3 key findings
python scripts/generate_schematic.py "POSTER FORMAT for A0. EXACTLY 3 cards: '95%' (150pt) 'ACCURACY' (60pt), '2X' (150pt) 'FASTER' (60pt), checkmark 'READY' (60pt). 50% white space. NO other text." -o figures/conclusions.png
```

## Workflow for PPTX Poster Creation
### Stage 1: Planning
1. **Confirm PPTX is explicitly requested**
2. **Determine poster requirements:**
- Size: 36×48 inches (most common) or A0
- Orientation: Portrait (most common)
3. **Develop content outline:**
- Identify 1-3 core messages
- Plan 3-5 visual elements
- Draft minimal text (300-800 words total)
### Stage 2: Generate Visual Elements (AI-Powered)
**CRITICAL: Generate SIMPLE figures with MINIMAL content.**
```bash
mkdir -p figures
# Generate each element with POSTER FORMAT specifications
