I’m an undergrad studying ISyE at the moment and was wondering what software people in industry would use for data analytics. I am currently learning how to use Tableau and Python (pandas, geopandas, etc.), but should I be gaining exposure in other tools as well?
Tableau and Python are a great start for data analytics tools. However, other great software that I would recommend learning are MATLAB and R. MATLAB can be absolutely wonderful for visualisations, a fast alternative to writing up your own algorithms if you can make use of its built-in equation solvers an powerful simulation environment, and all right for rapidly creating prototypes of numerical computation programs. As for R, it is specialized for statistical computing but is also great for machine learning, data visualization and analysis, and some areas of scientific computing. When compared to Tableau, R offers more flexibility in data manipulation and visualisation via its numerous packages such as tidyverse and ggplot, even though it does require more laborious coding.
Python have some powerful packages for data visualization. Also you can use Java Script to generate nice figures. Also, one advice on data visualization is to think about how would you present a set of data on a slide, I found this very helpful when preparing presentations.
