Themes — themes • cograph

A theme is a CographTheme object that sets the background, node, edge and label colors of a plot. Themes are stored in a registry and selected by name through the theme argument of splot, soplot and sn_theme. The functions theme_cograph_*() return the built-in themes:

theme_cograph_classic(): Blue nodes and gray edges ("classic").
theme_cograph_colorblind(): Colors distinguishable under color vision deficiency ("colorblind").
theme_cograph_gray(): Black and white for print ("gray", also "grey").
theme_cograph_dark(): Dark background for presentations ("dark").
theme_cograph_minimal(): Thin borders and few colors ("minimal").
theme_cograph_viridis(): The viridis palette ("viridis").
theme_cograph_nature(): Earth tones ("nature").

register_theme() adds a theme under a new name, get_theme() returns a registered theme, and list_themes() returns the names of all registered themes.
