| 151 | + |
| 152 | +## Recommended Next Steps |
| 153 | + |
| 154 | +1. **Create missing directory:** |
| 155 | + ```bash |
| 156 | + mkdir -p static/img/chapter-4 |
| 157 | + ``` |
| 158 | + |
| 159 | +2. **Source images from original SICP.js:** |
| 160 | + - Many of these figures likely exist in the [source SICP JS repository](https://github.com/source-academy/sicp) |
| 161 | + - Can be adapted from [HTML5/EPUB3 version](https://github.com/sarabander/sicp) |
| 162 | + |
| 163 | +3. **Priority order for image creation:** |
| 164 | + - **Priority 1:** Chapter 3.3.x diagrams (most critical for understanding data structures) |
| 165 | + - **Priority 2:** Chapter 4.1.x diagrams (essential for evaluator comprehension) |
| 166 | + - **Priority 3:** Chapter 3.5.x diagrams (signal processing concepts) |
| 167 | + |
| 168 | +4. **Image format:** |
| 169 | + - Prefer SVG format (scalable, matches existing images) |
| 170 | + - Use consistent naming: `ch[N]-Z-G-[num].svg` or `Fig[N].[num].svg` |
| 171 | + |
| 172 | +--- |
| 173 | + |
| 174 | +## Image Organization |
| 175 | + |
| 176 | +The image directory structure has been standardized to a consistent `chapter-N/` pattern: |
| 177 | + |
| 178 | +### Current Structure ✅ |
| 179 | +``` |
| 180 | +static/img/ |
| 181 | +├── chapter-1/ # 5 images (complete) |
| 182 | +│ └── ch1-*.svg |
| 183 | +├── chapter-2/ # 5 images (complete) |
| 184 | +│ └── ch2-*.svg |
| 185 | +├── chapter-3/ # 13 images (partial - 16+ missing) |
| 186 | +│ └── ch3-*.svg, Fig3.*.svg |
| 187 | +├── chapter-4/ # 0 images (directory created, awaiting images) |
| 188 | +│ └── (empty - all images missing) |
| 189 | +└── chapter-5/ # 5 images (partial - more needed) |
| 190 | + └── ch5-*.svg, Fig5.*.svg, *.png |
| 191 | +``` |
| 192 | + |
| 193 | +All markdown references have been updated to use the new paths. |

| 250 | +### Benefits of Mermaid |
| 251 | + |
| 252 | +1. **No external files** - diagrams defined directly in markdown |
| 253 | +2. **Version controlled** - changes tracked as text in git |
| 254 | +3. **Easy to update** - community can edit without image tools |
| 255 | +4. **Consistent styling** - unified visual appearance |
| 256 | +5. **Accessible** - better than static images for screen readers |
| 257 | + |
| 258 | +### Configuration |
| 259 | + |
| 260 | +Mermaid support enabled in `docusaurus.config.js`: |
| 261 | +```javascript |
| 262 | +markdown: { |
| 263 | + mermaid: true, |
| 264 | +}, |
| 265 | +themes: ['@docusaurus/theme-mermaid'], |
| 266 | +``` |
| 267 | + |
| 268 | +Package installed: `@docusaurus/theme-mermaid@3.9.2` |
| 269 | + |
| 270 | +--- |
| 271 | + |
| 272 | +## Notes |
| 273 | + |
| 274 | +- All existing Chapter 1, 2, 3 (partial), and 5 (partial) images are present and working |
| 275 | +- The original SICP book contains all these diagrams, they just need to be converted/adapted to JavaScript syntax |
| 276 | +- Mermaid is excellent for data structures but complex circuits/signal diagrams may need SVG or React components |
| 277 | +- Consider sourcing remaining images from upstream repositories that have already adapted SICP figures for JavaScript |
