## What it does

Reach for this skill when the risk is analytical distortion, not rendering difficulty. It covers distributions, intervals, uncertainty, missingness, aggregation effects and the usual ways a chart misleads. The default assumption is blunt: if a claim depends on variability, estimation, sampling or model uncertainty, the visualization should show it.

The working pattern runs in four steps. First, figure out whether the viewer needs exact values, distributions, intervals or model-derived estimates. Then pick encodings that show spread, uncertainty, missingness and sample size honestly. Next, check that aggregation or smoothing has not summarized away the variation the decision depends on. Short explanations go next to the view when the uncertainty concept is not obvious. Reference files cover summary choices, uncertainty encodings, analytical pitfalls and missingness.

What you get back is the statistical question named in words, a reason the chosen encoding is more truthful than the tempting alternative, and a flag wherever aggregation or interval choice can mislead. The skill ships in the `openai/plugins` repository under the MIT license.

## When to use it
- show spread instead of one average line
- pick between histogram, box plot and density plot
- draw confidence intervals without misleading readers
- surface missing data and sample size on a dashboard
- spot where aggregation eats the variation that matters

## Example prompts
- What chart should I use to show uncertainty in this data?
- Should this be a histogram, box plot, violin plot, or density plot?
- This dashboard hides variability. How should I fix it?

# Statistical and Uncertainty Visualization

## Overview

Use this skill when the risk is analytical distortion rather than rendering difficulty. This skill focuses on distributions, intervals, uncertainty, missingness, aggregation effects, and common statistical storytelling failures.

Default assumption: if a claim depends on variability, estimation, sampling, or model uncertainty, the visualization should show that explicitly.

## Working Pattern

1. Identify whether the viewer needs exact values, distributions, intervals, or model-derived estimates.
2. Choose encodings that show spread, uncertainty, missingness, or sample size honestly.
3. Avoid summarizing away the variation that matters to the decision.
4. Pair concise explanations with the view when the uncertainty concept is nontrivial.

## Output Expectations

- Name the statistical question, not just the chart type.
- Explain why the chosen encoding is more truthful than the tempting alternative.
- Call out when aggregation, smoothing, or interval choice can mislead.

## Representative Prompts

- "What chart should I use to show uncertainty here?"
- "Should this be a histogram, box plot, violin plot, or density plot?"
- "How do I show confidence intervals without misleading people?"
- "This dashboard hides variability. How should I fix it?"
- "Help me visualize missing data and sample size honestly."
