+Virtual Environment (For Linux/MacOS)
 -------------------
 If you need system packages that conflict with the packages required for RDPlot, you can use a python virtual environment (see below).
 
 When you are inside a virtual environment, python ignores all system packages and instead uses a dedicated environment, allowing you to install packages with pip that would otherwise conflict with system packages and/or different versions. The pitfall is that you need to activate the environment each time you want to use the program.
 
 You can find more info on virtual environments at https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/.
