 ## Pseudocode
 We got inspired by this pseudo-code presented in the Paper "[DBSCAN Revisited](https://www.ccs.neu.edu/home/vip/teach/DMcourse/2_cluster_EM_mixt/notes_slides/revisitofrevisitDBSCAN.pdf)". Here, the reader could get a overview of the steps of the code.

 ## A cool visualization that explain the algorithm
 Now, I need to share with the world this amazing website created by [Naftali Harris](https://www.naftaliharris.com/), from this detailed [post](https://www.naftaliharris.com/blog/visualizing-dbscan-clustering/) about DBSCAN. I crop a gif from this interactive visualization because this way I hope would be easier for the reader connect all the information broughted above.
