Not sure if the original link was ever fixed, but Wikipedia’s Hasidic dynasty page actually has a solid breakdown. Also worth checking out the map HaLeiVi laid out above, really clear lineage from the Maggid through the Chozeh down to most of today’s big dynasties.
On a related note, if anyone’s into the visual side of all this, there’s a shop on Etsy called Kavana Collective that does canvas portraits of the Rebbes. Nice way to have that history on your wall. Heres the link https://kavanacollective.etsy.com
