Programming languages genealogical tree
Basic idea behind project reconstruct diagram above in D3:
Ctrl + Fand copy/paste
There are a lot of similar efforts and all of them have one big flow from my point of view. It is not very clear what influence-links mean. There are different relationship possible between languages. For example:
Superset or subset.
Inspiration or ideas
Many links between languages in simillar projects not provide information on what kind of relation it is and lacks credibility. So they tends to be more confusing rather than helpfull. I want to add this type of information.
Other side of this project is to show in what language concept (idea, paradigm, technique) first appeared. See link. So if similar concept appears in other language it is can be considered as inspired by original source. But this not alway true: Simula considered to be first object-oriented language (even though there was idea of object before [citation required]), but idea of object-oriented language presented in SmallTalk is completley different and both languages appeared with small time difference, so I do not consider that one was inspired by another. Yes, both languages talk about object, but OOP-ideas behind them are completley different.
Add info about authors to programming languages.
Add concpets and their connection to languages.
Add links to scientific papers behind language concepts. - http://bibliography.selflanguage.org/ - https://github.com/rust-lang/rust-wiki-backup/blob/master/Note-research.md
It is possible to add mathematical theories which were preceding programing languages, like lambda calculus can be considered as parent of s-expressions (LISP) [citation required]. Haskell has roots in category theory [citation required].
