Data Visualization in Python

Dates

17th-20th October 2022

Due to the COVID-19 outbreak, this course will be held online

 

General Topic

Data manipulation and visualization for science-oriented applications using Python

Overview

Data is everywhere, we are drowning in it, and still grasping for insights. Plots and infographics can greatly help to highlight hidden trends in the data, or to present the final results of a project, or to convey a message. Part technique, part craft, data visualization is an important tool for any field that produces and digests numbers.

In this course we’ll learn how to organize a data-visualization project, from initial data cleanup and preparation to actual visualization. We’ll cover best (and worst) practices, and we’ll see many self contained exercises that will familiarize the student with different plot types, from classical line and bar charts, to maps, networks and subplots.

Intended Audience

The course is structured in modules over four days. Each day will include one or more lectures with class discussions of key concepts and practices, plus practical hands-on sessions with collaborative exercises where students will interact with the whole class and instructors to apply the acquired skills. After and during each exercise, results will be interpreted and discussed.

In practical terms, the students will be required to write code in the form of jupiter notebooks, plus standard python scripts. To do so there two main options:

  • online with a google account, use google drive and colab
  • locally, installing jupiter on your own computer

Assumed Background

The course is aimed at students, researchers and professionals interested in improving their data visualization skills. While science-oriented problems are the most common application, any field that produces data could be fertile ground for data visualization.

Some familiarity with Python is required, but attendants are not expected to be masters. If you want to improve your Python skills in preparation for the course, please have a look at these exercise: https://github.com/ne1s0n/bioinformateachers/tree/main/python_exercises

Learning outcomes

At the end of the course the student will have an understanding of:

  • the best practices for organizing a data-visualization oriented project
  • the worst practices (to avoid!) when you are presenting data
  • how to manipulate the initial data using the well known libraries numpy and pandas
  • how to implement the most common chart types…… and some of the more obscure ones
  • how to implement simple interactive charts
  • a general understanding of the seaborn library
  • how to adapt the many examples seen in the course to real world applications

Program

The course is from Monday to Thursday, 9:30 to 17:30 CET, with a lunch break (13:00 - 14:00) and a few breaks between exercises.
The pace of the course will be tuned on the students’ familiarity with python (or lack thereof). Theoretical lessons will be paired with hands-on exercises so that the student will try right away what has been explained. In general the course will follow a “learn by doing” approach, spawned by the belief that this kind of skill can only be acquired through direct experience.
All the code we’ll encounter will remain with the students after the course and will be easily adapted to their future needs and problems.
