Are you sure it's unclear to use commas and parentheses? Is being frowned upon by English professors really the same as being unclear?
Language means compressing and serializing information. Commas and parentheticals are a more efficient way to leave the information in a slightly more compressed state. Generally we are describing a graph serially, and adding the details as we go rather than coming back one by one and zooming in is just more efficient.
Also, I honestly suspect that often people just don't have the detailed level of understanding to be able to add it on the first level. And those details can be quite critical.
I mean, also the actual amount of things that are relevant that they have to say may make their communication seem cluttered compared to someone with a more simplistic knowledge base and thought process.
