 The best way for exploration is through jupyter / jupyter-lab notebooks. This is excellent for experimenting with interactive notebooks or
 to document the ideas you are working on. You have to install `jupyter` / `jupyter-lab` and `rapaio-jupyter-kernel` kernel. 
 For more information you can follow the instruction from
 [Rapaio Jupyter Kernel](https://github.com/padreati/rapaio-jupyter-kernel#installation).
