I am trying to make my way through this pdf but the example files are missing data. Most of the objects are either empty (if they are to have a stored value) or have angled stripes in their place.
I am new to all of this and trying to make some progress. I was able to recreate a lot of the data to approximate earlier lessons, but now that I am on chapter 3, things are bit more complicated without being able to follow along with examples of “Advanced Data Trees”.
If I am missing something, please let me know. Also, in the meantime, if anyone has and solid examples of data tree educational material, please do share.
Thank you in advance.
