Ran the bundled data_storyteller.py on a synthetic 200-row sales CSV with one planted outlier: it caught exactly that row (outlier_pct 0.5%), flagged the resulting right-skew (skewness 7.13), found the real marketing-spend/revenue correlation (r=0.52), and wrote a clean plain-English executive summary - fully working, not a stub.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 5/5

What Data Storyteller does

A bundle of eleven Python scripts (profiling, quality audit, correlation, outliers, stats, pivots, A/B tests, ROI, budget, surveys, time-series) fronted by one entrypoint that produces an HTML/PDF/JSON narrative report from a CSV or spreadsheet. Use for exploratory data analysis or executive-ready write-ups where you want auto-generated plain-English findings, not just numbers.
