MindMap brings mind-map, timeline, and catalog / organisation-chart diagrams to Manim. It is bundled inside manim_extensions as the manim_extensions.mindmap subpackage and is also kept as a Git submodule under third_party/.

Features

• Node – the basic tree-node class.

• MindMap / StandardMap – mind-map classes with multiple layout directions.

• CatalogMap – organisation / directory-structure diagrams.

• TimeLine – timeline diagrams.

• Animation helpers: LayoutAnimation, InsertNode, RemoveNode, ScaleNode, AlterNode.

• Styling / layout options: NodeStyle, LayoutType, LayoutConfig.

Quick start

Import directly from manim_extensions (from manim_extensions.mindmap import *).

Inserting nodes into a mind map

Example: MindMapInsertExample

from manim import *
from manim_extensions.mindmap import Node, InsertNode

class MindMapInsertExample(Scene):
    def construct(self):
        root = Node(MathTex("Root", font_size=36).to_edge(LEFT))
        a1 = Node(MathTex("A1", font_size=36))
        a2 = Node(MathTex("A2", font_size=36))
        a3 = Node(MathTex("A3", font_size=36))

        self.play(
            InsertNode(self, {root: [a1, a2, a3]}),
            run_time=2,
        )

from manim import *
from manim_extensions.mindmap import Node, InsertNode

class MindMapInsertExample(Scene):
    def construct(self):
        root = Node(MathTex("Root", font_size=36).to_edge(LEFT))
        a1 = Node(MathTex("A1", font_size=36))
        a2 = Node(MathTex("A2", font_size=36))
        a3 = Node(MathTex("A3", font_size=36))

        self.play(
            InsertNode(self, {root: [a1, a2, a3]}),
            run_time=2,
        )

Building a tree with LayoutAnimation

Example: LayoutAnimationExample

from manim import *
from manim_extensions.mindmap import Node, LayoutAnimation

class LayoutAnimationExample(Scene):
    def construct(self):
        root = Node(MathTex("Root", font_size=36).to_edge(LEFT))
        a1 = Node(MathTex("A1", font_size=36))
        a2 = Node(MathTex("A2", font_size=36))
        a21 = Node(MathTex("A2-1", font_size=36))
        a22 = Node(MathTex("A2-2", font_size=36))

        root.add_child(a1)
        root.add_child(a2)
        a2.add_child(a21)
        a2.add_child(a22)

        self.play(LayoutAnimation(self, root))

from manim import *
from manim_extensions.mindmap import Node, LayoutAnimation

class LayoutAnimationExample(Scene):
    def construct(self):
        root = Node(MathTex("Root", font_size=36).to_edge(LEFT))
        a1 = Node(MathTex("A1", font_size=36))
        a2 = Node(MathTex("A2", font_size=36))
        a21 = Node(MathTex("A2-1", font_size=36))
        a22 = Node(MathTex("A2-2", font_size=36))

        root.add_child(a1)
        root.add_child(a2)
        a2.add_child(a21)
        a2.add_child(a22)

        self.play(LayoutAnimation(self, root))

Layout types

The layout_type argument of the animation classes accepts:

• LayoutType.MindMap – default mind-map layout.

• LayoutType.Standard – left/right or top/bottom two-sided layout.

• LayoutType.TimeLine – timeline layout.

• LayoutType.Catalog – top-down catalog / directory layout.

See the original README for full animated demos and the complete API.
