以下是您提供的内容的中文翻译：
"manim可以使用LaTeX，LaTeX可以使用Tikz，Tikz可以沿着路径排版文本，所以..."
class Test(Scene):
def construct(self):
s = "巴士上的车轮转" + "，".join(["一圈又一圈"]*3)
txt = " ".join(展开收缩*7)
myTexTemplate = TexTemplate()
myTexTemplate.add_to_preamble(r"\usepackage{tikz}\usetikzlibrary{decorations.text}")
tikz_code = rf"""\sffamily\scriptsize
\begin{{tikzpicture}}[
decoration={{
reverse path,
text effects along path,
text={{{txt}}},
text effects/.cd,
text along path,
}}
]
\draw [decorate] (0,0)
\foreach \i [evaluate={{\r=0.3+(\i/1500);}}] in {{0,5,...,4490}}{{ -- (\i:\r)}};
\end{{tikzpicture}}
"""
t = Tex(tikz_code, tex_template=myTexTemplate).scale(0.8)
self.play(Write(t), run_time=10)
self.wait(2)
结果：
英文:
Well, manim can use LaTeX, and LaTeX can use Tikz, and Tikz can typeset text along a path so...
