This is a follow up post to Part I that covered new functionalities in
DataFrames.jl release 0.21, which you can find here.

New material

I have created two additional notebooks that can be downloaded from
this GitHub Gist.

The content is shared as two notebooks:

1. airports.ipynb that mostly focuses on transformation operations and
   the syntax source => function => sink.
2. bison.ipynb that discusses new functionalities related to population of
   data frames with heterogeneous data that were added to push! and append!.

I hope you will find the new examples useful.

Environment setup

The codes were tested under Julia 1.4.1.

Please make sure that you download all materials from the Gist. In particular
having proper Project.toml and Manifest.toml files will ensure that you have
right versions of the packages that were used.

Also note that for the first part of the tutorial (airports.ipynb) you need to
download the file I used from Kaggle (it is quite large). For the second
notebook bison.ipynb the JSON file bison.json is bundled in the gist.

If you would have any questions regarding the materials please do not hesitate
to contact me.
