I'm specifically looking for two kinds of visualizations:
1. A visualization that puts PLs into application domains: Something like a Venn diagram of the domains covered in [2] would be great.
2. A visualization that shows a timeline of programming languages and how they branch off from another: Something like [0], but with more PLs. Perhaps with the data of [3], but visualized. I know of a visualization that does this for Linux distros [4].

Any other visualizations about programming languages that you deem beautiful would be greatly appreciated as well. Some visualizations I found along the way:
