And I can also recommend the thread from @SciByDegrees that started me down this road

A thread which kicks-off a debate about Desert Island Graphs and the merits (various) of the BEPN Diagram

Which in turn led to me learning about the TriLinear Chart of the #Nuclides

And finding this useful #Isotopes Browser app from @iaeaorg

And this excellent explanation of how the #HertzsprungRussell diagram originated

And this on the Valley of Stability

Again, HT @A_Weatherall

And this slide deck for Teaching the #HertzsprungRussell diagram
