xcode-select --install
```
Make sure you have Homebrew installed.

Linux (Debian-based)

Install GraphViz by running

sudo apt-get install graphviz
```

Install gnuplot by running

sudo apt-get install gnuplot gnuplot-x11

Windows

Download and install GraphViz. We recommend you place this in C:\Program Files (x86).
Download and install gnuplot. Check the box to add gnuplot to the environment variables (or Path). We recommend you place this in C:\Program Files (x86).
Set your Path system environment variable so that the installed programs can be found easily. Go to the Settings and then edit the value for the variable Path (which is in the list of System Variables) by appending the directories of gnuplot and GraphViz binaries. Make sure these paths are indeed correct. Here is an example of how your Path variable could look:
```
C:\Program Files (x86)\GraphvizX.XX\bin;C:\Program Files (x86)\gnuplot\bin
```
