I've not used any of those languages so I might be wrong, but from their description pages, there are two mayor salient differences: - Tersus doesn't have a textual representation, it's a purely visual language - Luna shows the data currently being processed besides the visual primitive that handles them. This second part may be invaluable. I worked with a Tersus-like flow language in the past, and building simple data-processing pipelines was a breeze; but debugging them to add more complex logic was a pain, because inspecting the current state of the graph is quite difficult - in special when there are nested loops.
