Couldn't the evidence in a graph, be presented in "digital" format, ie as just tables of numbers? Is it because graphs make it easier to see the underlying mathematical processes.Yes, humans are a very visual species.
- We have the unusual visual quirk that we can see things that don't change, which makes the whole "reading a book" possible.
- As I understand it, for most species, things that don't change do not generate an image.
Graphs work well in 2D.
- They can be extended to 3D on a page for some sets of data
- but I think 3D data would be explored more easily with virtual reality headsets
- I have seen one presentation (as a movie) that worked through data in more than 3 dimensions (I think it may have been 8 dimensions?). But that was geometrical data, so it was (sort of) possible to see geometrical patterns emerge as the view switched between hyperplanes. I don't this would work nearly so well for data that was noisy in multiple dimensions, as you would only see part of the pattern and part of the noise.
The one I saw was a bit more colorful than this one:
As BC said, regression can find patterns in multi-dimensional data that we wouldn't be able to visualise.
