We start from the MIT-licensed images contributed by Jeff Thompson from:

• http://nbviewer.ipython.org/github/jkthompson/pyspark-pictures/blob/master/pyspark-pictures.ipynb

as blogged here:

• http://data-frack.blogspot.com/2015/01/visual-mnemonics-for-pyspark-api.html

We split each page of the PDF:

• https://github.com/jkthompson/pyspark-pictures/blob/master/images/pyspark-pictures.pdf

as follows:

$ convert -density 300 visualapiJTK.pdf -quality 100 visualapiJTK.png

$ for file in *.png; do convert $file -resize 1000 med/$file; done
