Maps semantic style keys (:node, :edge, :arrow, etc.) to

edge_label: [:faint, :italic]
}
Boxart.render(graph, theme: my_theme)Summary
Functions
Returns a built-in theme by name.
Returns the ANSI format sequence for a style key.
Converts the theme to a map of style key => ANSI atoms. Useful for precomputing.
