[features]
default = []
# Plotly rendering: `Graph::to_plot`, `write_html`, `show`, `render` and the
# trace builders. `plotly` is declared without `static_export_default`, so
# this feature resolves no WebDriver, image export or async runtime package
# (ADR-0002 section 3).
plotly = ["dep:plotly"]
# PNG and SVG export (`Graph::write_png`, `write_svg`), drawn natively with
# Plotters: no browser, WebDriver, network or installed font (#927). It
# still implies `plotly`, so a `static_export` build keeps the interactive
# API. The text is read from the bundled Open Sans (SIL OFL 1.1,
# `assets/OFL.txt`) with skrifa; Plotters has no font feature, so no
# ttf-parser is resolved.

# docs.rs builds the default features, empty for this crate, so name the
# optional ones the API documents. `static_export` builds like any other
# feature since its export went native (#927): no build script, browser,
# network or system font (the font ships in `assets/`). #930 recorded an
# offline, warnings-denied documentation build of exactly this selection.
