+## Why this project
+
+This project can be especially useful in Jupyter notebooks to export your graphs in SVG, PDF, or PNG formats. While algorithms and computations can be handled with [NetworkX](https://networkx.org), it lacks the high-quality rendering capabilities needed for publication, which Gephi has and is designed for. 
+
+Moreover, it allows you to create a Gephi pipeline, which is useful when you need to generate the same type of map multiple times but with different data.
