执行下面的命令，否则“brew install graphviz”会有报错：Error: graphviz: Failed to download resource “libtiff”
brew update
若brew慢：mac使用brew update无反应,更新慢解决办法
brew install graphviz
graphviz的安装位置：“/opt/homebrew/Cellar/graphviz/3.0.0/lib/graphviz”
dot.exe位置： /opt/homebrew/Cellar/graphviz/3.0.0/bin

在dot位置执行
dot -v
(base) dulei@192 bin % ./dot -v
