There's an artist named Ward Shelley, who does this interesting thing where he makes hand-made "timelines" and data visualizations – the kind found in history books, but sometimes on strange or unusual or unexpected topics. I really like his stuff. Here's a timeline of the history of science fiction:
He calls these things "diagrammatic paintings." Also, here's an interesting quote,

way essential. Science fiction deals with improbable possibilities. It
has that in common with religion and patriotism, except SF is much more
candid about it.
