Are You a Data Viz Ninja? Take This Python Libraries Quiz to Find Out

Data visualization or ploting the data is a core skill for any data scientist or analyst. It’s the key to effectively communicating insights from data. But how well do you really know your Python libraries for visualization like Matplotlib, Seaborn and Plotly?

This 30-question quiz will put you to the test on everything from basic chart types to advanced concepts and technical skills. You’ll have 30 minutes to answer as many questions as possible. Your score will reveal how comfortable you are with visualizing data using the most popular Python packages.

What's Covered in the Data Visualization Quiz?

The questions cover the following topics:

Different chart types – When to use bar charts, line plots, scatter plots etc.
Python library functionality – Commands, parameters and methods in Matplotlib, Seaborn and Plotly
Best practices – Principles of effective visualization like labeling, whitespace and dimensionality reduction
Interactivity – Features that enhance understanding like tooltips, callbacks and filters
Advanced concepts – Facetting, overplotting, pivot tables, key differences between libraries

You’ll need to draw on both conceptual knowledge as well as hands-on experience with the libraries. Mixed question formats like multiple choice, true/false and coding keep you on your toes.

How Can You Benefit From Taking the Quiz?

Some benefits of giving this quiz a try include:

Evaluate your current data visualization proficiency objectively
Identify topics to focus more study on like advanced visualization techniques
Review functions and syntax you may have forgotten
Gauge if you’re ready for data scientist job interviews involving Python viz skills
Gain confidence in your abilities to present data in a clear, engaging way
Have fun challenging yourself while strengthening an essential data skill

Be sure to time yourself and track your score as you go through the questions. At the end, you’ll know exactly how much more practice you need to become an expert in data storytelling through Python libraries.

Are You Ready to Test Your Python Visualization Skills Now?

If you’re serious about assessing or improving your Python data visualization competence, then this 30-question quiz is a must-take challenge. Give yourself 8 minutes, go through each question carefully and see how you fare against visualization pros.

There seems some bug.
I attempted the quiz twice yesterday and could not complete it within the permissible time and quiz page closed itself.
But, instead of showing any results, it remained blank.
