+## Python Environment
+
+Use python environment for generating graph and experiments. Requires `venv`.
+
+```sh
+python3 -m venv .venv
+```
+
+Activate it by using the script inside the .venv `directory`.
+
+```sh
+.venv/Script/activate.sh
+```
+
+Install packages from the `requirements.txt`
+
+```sh
+pip install -r ./requirements.txt 
+```
