# Technical Document Extraction: Multi-Topic Influence Analysis
## Overview
The image contains four scatter plots (PCA visualizations) and one line graph (temporal analysis), analyzing influence dynamics across four topics: Russo-Ukrainian war, Covid, Cost-of-living crisis, and Brexit. Each plot uses Principal Component Analysis (PCA) to reduce dimensionality, with PC1 and PC2 axes explaining variance percentages. A line graph shows temporal trends in influence share.

## Line Graph: Temporal Influence Analysis
- **Title**: TE analysis
- **Axes**:
- X-axis: Week (0–50)
- Y-axis: Share of influence (%)
- **Lines**:
- Green: Leaders (fluctuates ~4% with peaks up to 6%)
- Yellow: Funnelers (stable ~2%)
- Purple: Receivers (stable ~0%)
- **Shading**:
- Confidence intervals (10% range) around each line.
- **Trend**:
- Leaders show volatility but remain dominant.
- Funnelers and Receivers exhibit minimal change over time.

## Spatial Grounding & Validation
- **Legend Placement**: Bottom-right corner of all scatter plots.
- **Color Consistency**:
- Green (Leaders) matches all green data points.
- Yellow (Funnelers) matches all yellow data points.
- Purple (Receivers) matches all purple data points.
- **Axis Labels**: All PC1/PC2 percentages and axis titles are explicitly stated.

## Additional Notes
- **Language**: All text is in English.
- **Data Structure**:
- Scatter plots use PCA for dimensionality reduction.
- Line graph tracks temporal influence share.
- **Missing Data**: No explicit data tables; trends inferred from visual patterns.
