# Scatter Charts Showcase

This demo consists of three files that work together:

- **charts-scatter.py** — Python script that calls `officecli` commands to generate the deck (9 slides).
- **charts-scatter.pptx** — The generated 9-slide deck.
- **charts-scatter.md** — This file. Maps each slide to the features it demonstrates.
