I did something similar many years ago, exporting my Facebook data and plotting a simple force-directed graph [1] of my network, it was quite interesting how meaningful groups and connections emerge: https://wechoosethemoon.es/assets/img/posts/colores.png
Very interesting! This tool only seems to collect the profile picture and provide a basic laggy interface to view it. Likely the tool you used previously for this dones't work thanks to API Facebook changes.
