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.
Usage:
pip install officecli-sdk # plus the `officecli` binary on PATH
python3 charts-waterfall.py
