Doughnut Charts Showcase — generates charts-doughnut.pptx exercising the pptx
`chart` element with chartType=doughnut across 8 slides.
Slide 1 holeSize variants holeSize=10/30/55/75
Slide 2 Multi-ring two-series + three-series concentric rings
Slide 3 firstSliceAngle 0 / 90 / 180 / 270
Slide 4 Data labels percent / category / value, leaderlines, labelfont
Slide 5 Series styling colors, gradient, seriesoutline, seriesshadow, transparency
Slide 6 Title & legend title.* + legend positions + legendFont
Slide 7 Backgrounds chartareafill, plotFill, chartborder, roundedcorners
Slide 8 Presets & per-series preset bundles + chart-series Set
SDK twin of charts-doughnut.sh (officecli CLI). Both produce an equivalent
charts-doughnut.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 `doc.batch(...)` round-trips.
Each item is the same `{"command","parent","type","props"}` dict you'd put in an
`officecli batch` list. batch runs with force=True so a prop a future build
doesn't yet support is skipped (forward-compat) rather than aborting the run.
Usage:
pip install officecli-sdk # plus the `officecli` binary on PATH
python3 charts-doughnut.py
