Thanks for putting it in such clear words. I thought about "micro" vs "macro", but chronology vs topology is much much better. There are micro algorithms that i wouldn't try to put in diagrams, and huge data mappings that i would perfectly understand with simple arrows and boxes.
Thanks for the kind words! My doctorate was about a DSL for musical signal processors [1]. Current post doc is about programming interfaces - I hope to Show HN in a couple of months!
Are you working in that particular field ?
