This class inherits its label properties from `LabeledLine`, so the main parameters controlling it are the same.

Default value is 0.5. label_config A dictionary containing the configuration for the label.

Parameters ---------- vertex_groups Vertices passed to the :class:`~.Polygram` constructor. label Label that will be displayed on the Polygram. precision The precision used by the PolyLabel algorithm. label_config A dictionary containing the configuration for the label. This is only applied if ``label`` is of type ``str``. box_config A dictionary containing the configuration for the background box. frame_config A dictionary containing the configuration for the frame. .. note:: The PolyLabel Algorithm expects each vertex group to form a closed ring. If the input is open, :class:`LabeledPolygram` will attempt to close it. This may cause the polygon to intersect itself leading to unexpected results. .. tip:: Make sure the precision corresponds to the scale of your inputs! For instance, if the bounding box of your polygon stretches from 0 to 10,000, a precision of 1.0 or 10.0 should be sufficient.
