langchain_core.runnables.graph_ascii.draw_ascii(vertices: Mapping[str, str], edges: Sequence[Edge]) → str

构建一个有向无环图（DAG）并用ASCII图形表示出来。

参数:

vertices (list): 图的顶点列表。 edges (list): 图的边列表。

返回:

str: ASCII表示形式

示例:

>>> vertices = [1, 2, 3, 4]
>>> edges = [(1, 2), (2, 3), (2, 4), (1, 4)]
>>> print(draw(vertices, edges))
