Question:
*Hi, I am a student from Swansea University that as part of an assignment we are to visualise datasets from the Project tycho datasets : https://www.tycho.pitt.edu/ . In this assignment we need to produce a treemap in which we need to describe its features such as:
-
its data hierarchy
-
what the leaf node size is mapped too
-
how the leaf nodes are laid out
-
what are the internal nodes mapped too
-
what tree node layout algorithm is used
My question therefore is, is there a way to retrieve this data from tableau so that I can be sure what layout algorithm has been used or to know how the leaf nodes have been positioned or do I have to use resources such as https://en.wikipedia.org/wiki/Treemapping and attempt to match the output to the algorithm (in this case)?
