#!/usr/bin/env python3 """ Waterfall Charts Showcase — increaseColor / decreaseColor / totalColor. Generates: charts-waterfall.pptx Slide 1 Basic default colors, single dataset Slide 2 Color schemes increaseColor / decreaseColor / totalColor combinations Slide 3 Title & legend Slide 4 Data labels Slide 5 Axes min/max, gridlines, axisnumfmt (currency) Slide 6 Backgrounds chartareafill, plotFill, chartborder, roundedcorners Slide 7 Larger story a real cashflow waterfall with labels Slide 8 Presets SDK twin of charts-waterfall.sh (officecli CLI). Both produce an equivalent charts-waterfall.pptx. This one drives the **officecli Python SDK** (`pip install officecli-sdk`): one resident is started and every slide, title shape and chart is shipped over the named pipe in a single `doc.batch(...)` round-trip. Each item is the same `{"command","parent","type","props"}` dict you'd put in an `officecli batch` list.
