# Case A: Continual Meta-Learning — Image Generation Prompt

## Prompt

A premium, modern data visualization infographic on a clean white background with subtle light-gray grid lines. The chart is a **line chart** showing progressive performance improvement across 5 data points on the X-axis (labeled "Self-Iteration Round").

**Overall title** at the top in bold dark navy sans-serif font: "Case A: Continual Meta-Learning for Few-Shot Adaptation"

**Y-axis:** "Few-Shot Accuracy (%)" ranging from 15% to 105%. **X-axis:** "Self-Iteration Round" with 5 labeled tick marks.

**Data points and line:**
- Point 0 (Baseline): 25.9% — large circle marker, colored **slate gray** (#757575). X-label below: "Baseline" with a small gray beaker/flask icon, subtitle "(Initial Code)".
- Point 1 (Iter 1): 81.2% — large circle marker, colored **emerald green** (#2E7D32). X-label: "Iter 1" with a small green brain/neural-network icon, subtitle "(Deep Encoder + Meta-SGD)".
- Point 2 (Iter 2): 77.5% — large circle marker, colored **crimson red** (#C62828). X-label: "Iter 2" with a small red warning-triangle icon, subtitle "(Prototype Net — Regression)".
- Point 3 (Iter 3): 93.4% — large circle marker, colored **emerald green** (#2E7D32). X-label: "Iter 3" with a small green rocket icon, subtitle "(Linear Clf + L2 Anchor)".
- Point 4 (Iter 4): 93.4% — large circle marker, colored **slate gray** (#757575). X-label: "Iter 4" with a small gray checkmark-circle icon, subtitle "(Converged)".

**Connecting line:** Thick (3px) solid line in **royal blue** (#1565C0) connecting all 5 points in order. The area below the line (above the baseline value of 25.9%) is filled with a very light semi-transparent blue wash (#1565C0 at 8% opacity).

**Annotations with callout arrows:**
- Near Point 1: A green callout box with text "+55.3 pts" in bold green, below it "Deep encoder + context-gated replay" in smaller green text. A thin green arrow points from the callout to Point 1. Include a small upward-arrow icon.
- Near Point 2: A red italic callout "Prototype net too simple" with a thin red arrow pointing to Point 2. Include a small X-mark icon.
- Near Point 3: A green callout box with text "+15.9 pts" in bold green, below it "Linear clf + L2 anchor + cosine gating" in smaller green text. A thin green arrow points from the callout to Point 3. Include a small upward-arrow icon.

**Reference line:** A horizontal **dashed orange line** (#E65100) at y=100% with a small label "Oracle (100%)" at the right end in italic orange text. Include a small trophy/target icon next to the label.

**Summary stats box:** Upper-left corner, a rounded rectangle with light blue background (#E3F2FD) and blue border (#1565C0), containing monospace text:
```
Baseline: 25.9%  →  Best: 93.4%
Improvement: +67.5 pts (261% rel.)
```

**Legend** at the bottom center with three items, each with a colored square swatch:
- Green square: "Improved"
- Red square: "Regressed (auto-recovered)"
- Gray square: "No change / Baseline"

**Style:** Clean, professional, tech-forward aesthetic. Use a modern sans-serif font (like Inter, SF Pro, or Helvetica Neue). Subtle drop shadows on the summary box and annotation callouts. Smooth anti-aliased lines. The overall feel should be suitable for a top-tier AI research company's product page or investor deck — polished, data-rich, and visually compelling. High contrast text. No 3D effects. Flat design with depth through subtle shadows and layering.

**Dimensions:** 1200 x 900 pixels, 2x retina resolution.
