Working in any science should also make this argument clearer. Data as text is hard to read and communicate. Even explanations of results. But graphs? Those are worth a thousand words. They communicate so much so fast. There's also a lot of skill to doing this accurately and well, just as one can say about writing. A whole subfield of computer graphics is dedicated to data visualization because it's so useful. Including things like colors. Things people often ignore because it feels so natural and obvious but actually isn't.

I think it's naïve to claim there's a singular best method to communicate. Text is great, especially since it is asynchronous. But even the OP works off of bad assumptions that are made about verbal language being natural and not being taught. But there's a simple fact, when near another person we strongly prefer to speak than write. And when we can mix modes we like to. There's an art to all this and I think wanting to have a singular mode is more a desire of simplicity than a desire to be optimal
