Graph¶

Qualified name: algan.mobs.manim\_compat.Graph

class Graph(vertices, edges, labels=False, label_fill_color=ManimColor('#000000'), layout='spring', layout_scale=2, layout_config=None, vertex_type=<class 'algan.external_libraries.manim.mobject.geometry.arc.Dot'>, vertex_config=None, vertex_mobjects=None, edge_type=<class 'algan.external_libraries.manim.mobject.geometry.line.Line'>, partitions=None, root_vertex=None, edge_config=None)¶

Bases: ManimCompatMob

An undirected graph (vertices connected with edges).

The graph comes with an updater which makes the edges stick to the vertices when moved around. See DiGraph for a version with directed edges.

Parameters:

vertices (Sequence[Hashable]) – A list of vertices. Must be hashable elements.
edges (Sequence[tuple[Hashable, Hashable]]) – A list of edges, specified as tuples (u, v) where both u and v are vertices. The vertex order is irrelevant.
labels (bool | dict) – Controls whether or not vertices are labeled. If False (the default), the vertices are not labeled; if True they are labeled using their names (as specified in vertices) via MathTex. Alternatively, custom labels can be specified by passing a dictionary whose keys are the vertices, and whose values are the corresponding vertex labels (rendered via, e.g., Text or Tex).
label_fill_color (str) – Sets the fill color of the default labels generated when labels is set to True. Has no effect for other values of labels.
layout (LayoutName | dict[Hashable, Point3DLike] | LayoutFunction) – Either one of "spring" (the default), "circular", "kamada_kawai", "planar", "random", "shell", "spectral", "spiral", "tree", and "partite" for automatic vertex positioning using networkx (see their documentation for more details), or a dictionary specifying a coordinate (value) for each vertex (key) for manual positioning.
layout_config (dict | None) – Only for automatically generated layouts. A dictionary whose entries are passed as keyword arguments to the automatic layout algorithm specified via layout of networkx. The tree layout also accepts a special parameter vertex_spacing passed as a keyword argument inside the layout_config dictionary. Passing a tuple (space_x, space_y) as this argument overrides the value of layout_scale and ensures that vertices are arranged in a way such that the centers of siblings in the same layer are at least space_x units apart horizontally, and neighboring layers are spaced space_y units vertically.
layout_scale (float | tuple[float, float, float]) – The scale of automatically generated layouts: the vertices will be arranged such that the coordinates are located within the interval [-scale, scale]. Some layouts accept a tuple (scale_x, scale_y) causing the first coordinate to be in the interval [-scale_x, scale_x], and the second in [-scale_y, scale_y]. Default: 2.
vertex_type (type[Mobject]) – The mobject class used for displaying vertices in the scene.
vertex_config (dict | None) – Either a dictionary containing keyword arguments to be passed to the class specified via vertex_type, or a dictionary whose keys are the vertices, and whose values are dictionaries containing keyword arguments for the mobject related to the corresponding vertex.
vertex_mobjects (dict | None) – A dictionary whose keys are the vertices, and whose values are mobjects to be used as vertices. Passing vertices here overrides all other configuration options for a vertex.
edge_type (type[Mobject]) – The mobject class used for displaying edges in the scene.
edge_config (dict | None) – Either a dictionary containing keyword arguments to be passed to the class specified via edge_type, or a dictionary whose keys are the edges, and whose values are dictionaries containing keyword arguments for the mobject related to the corresponding edge.
partitions (Sequence[Sequence[Hashable]] | None)
root_vertex (Hashable | None)

`normalized_basis`	The Mob's orientation with scale divided out, shape `(*, 9)`.
`parents`	The Mobs this one is attached to, in attachment order.

`right`	Get the Mob's own rightward direction.
`scale_coefficient`	The Mob's scale along its own right, up and forward axes, shape `(*, 3)`.
`stroke_color`	The color of the circuit's border stroke.
`two_sided`	Whether this Mob's geometry should be lit from whichever side the ray arrives on.
`up`	Get the Mob's own upward direction.
