How to interface Python with Qlikview for data visualization?
There's no straightforward route to calling Python from QlikView. I have used this:

Create a Python program that outputs CSV (or any file format that QlikView can read)
Invoke your Python program from the QlikView script: EXEC python3 my_program.py > my_output.csv
Read the output into QlikView: LOAD * FROM my_output.csv (...)

Note that the EXEC command requires the privilege "Can Execute External Programs" on the Settings tab of the script editor.
I am using Scikit-Learn and Pandas libraries of Python for Data Analysis.
