• Class Brace(TexMobject)
• Class BraceLabel(VMobject)
• Class BraceText(BraceLabel)

Class Brace(TexMobject)

Brace is used to create a brace of the specified Mobject for specified parameters.

Class BraceLabel(VMobject)

BraceLabel is used to create a brace with TexMobject label for specified parameters.

Class BraceText(BraceLabel)

BraceText is used to create a brace with TextMobject text for specified parameters.
