At Uni I am currently taking data visualization as a course. While reading thru the script I stumbled upon two examples for one dimensional data. Example one: Bus stops with their name and order (current -> next bus stop). Example two: A list of values (not a set!)(the type of value does not matter for the sake of simplicity).
Now I am wondering how an ordered list can be two dimensional. To me it looks like two dimensional data. The first dimension being the index, the second one being the value. For the first example the two dimensions could be the station name and the next stations name.
Since v(t) is considered as two dimensional data (according to my Prof) I am wondering why value(index) us not two dimensional data.
Representation wise I can understand why the data can be represented one dimensional, since they can be represented in a straight line. But feature wise I don't understand how value(index) and v(t) are different.
Please enlighten my mind since the prof only told me to stick to the script...
