| name | Chart Interpretation |
| description | Read any chart or data visualization, extract insights, detect patterns and anomalies, check for bias, and construct a narrative. |
Purpose
Decode any chart (screenshot, embedded image, slide visual) into actionable insights. Charts can inform or mislead. This skill teaches how to read them critically, extract what matters, and spot what's hidden or distorted.
Steps
- Identify the chart type: bar, line, pie, scatter, area, combo, heatmap, treemap, funnel
- Read the axes: What's measured? What units? What time range? Are axes truncated?
- Decode the encodings: What do colors, sizes, positions, and shapes represent?
- Find the story: What's the main takeaway? What trend or comparison is shown?
- Check for bias: Is the visualization honest or misleading?
- Extract the narrative: Write what this chart tells the audience

| Pie/Donut | Circle divided into segments | Part-of-whole (max 5 slices) |
| Scatter | Dots in 2D space | Correlation between variables |
| Area | Filled region under a line | Volume/composition over time |
| Heatmap | Color grid | Density or intensity patterns |
| Funnel |
