We are excited to announce that the 3rd annual Student Dataviz Challenge is confirmed for 2022, in partnership with UNICEF, Tableau & Mazars and EDHEC Business School. Together we want to promote the importance of data visualization, encourage the development of data-based decision making in future managers and support UNICEF mission.

“Data is a strategic asset to create a more just and equal world. When the right data is in the right hands at the right time, decisions can be better informed, more equitable and more likely to protect children's rights.”


If you are passionate about data, or if you would like to practice and improve your data visualization skills whilst supporting UNICEF mission, the Student Dataviz Challenge 2022 is an ideal opportunity for you to make a difference and put your skills to the test alongside of hundreds of other students across Europe.

It is a unique competition designed to put theory into practice and have fun with the data using Tableau software and open data provided by UNICEF. The top 10 entries will present their visualization to the judges and partners and compete for the opportunity to interview with UNICEF for a Data Visualization internship.

Panel discussion

Data Viz Discussions: Why is data visualisation important for business and your career?

Being able to make informed, data-based decisions is a critical skill for any manager and the field of data visualisation has grown rapidly in the past few years to ensure that businesses can make informed, reliable choices and identify key trends.

But is data visualisation something only data analysts and specialists need? If you don’t want a career in data viz, statistics or analytics why would you want to learn about data visualisation or practice this skill?

In this Data Viz Discussion, we ask experts from Mazars, Tableau, and MBA alumnus and EDHEC MBA Director their views on why data visualisation is important for organisations and future managers and leaders.

What skills are in demand on the market? Is data visualisation valued by employers?

Among the top 10 job skills for 2025 identified by the World Economic Forum are analytical thinking, complex problem solving, critical thinking and analysis, creativity and originality, and technology use. So, what is really interesting is that data visualisation is a combination of all these skills, blending the hard data analytical skills with the ability to communicate ideas effectively.

Of course, other skills are also in demand on the market such as active learning, innovation, leadership, programming, resilience, stress tolerance and flexibility.

Yet, today, the rising demand for data literacy on the job market is undeniable across all sectors, industries and job roles. Indeed from tech, consulting, finance, retail, healthcare, logistics to politics, there is a real need for data communicators in order to harness the power of big data, gain valuable insights and make informed business decisions. And this no matter the size of the organisation.

In terms of job opportunities, this translates into a high demand for data scientists and analysts, but also business intelligence specialists, across all functions in organisations: marketing, finance, HR, L&D, operations, sales…

Nowadays, everything can be measured and monitored. Being able to make sense of this mountain of data, share with colleagues and clients efficiently, and make successful decisions over time makes data visualisation one of the most in demand skills on the market.

Jessica Wheaton, Learning & Culture Manager, Mazars Group


Is data visualisation important for companies?

It's difficult to think of a company that doesn't benefit from making data understandable. As we know, the age of 'Big Data' has transformed the way we capture, utilise, and interpret all of the data collected around us. Organizations realize the full value of their data when they’re truly data-driven: When everyone—across all levels and roles—is empowered to make better decisions using data, every day with a Data Culture.

As Jessica said, everything is now measured and monitored. Data visualisation helps us to tell stories by structuring data into a form that's easier to understand, highlighting trends and outliers. A good visualisation tells a story that's easier to understand.

Companies use data visualisation to drive insights that allow them to make better decisions and to better serve their customers and stakeholders. By seeing and understanding certain patterns in their data, companies are then able to identify red flags and/or opportunities, and thus drive business ahead.

Data literacy is increasingly vital to modern organizations. While 83 percent of CEOs expect their organizations to be more data-driven, people often lack essential data skills with only 33 percent of employees comfortable using data analytics to support their decisions. Tableau Academic Programs aims to empower the next generation of professionals with the data skills they need to succeed in the modern workforce. Since 2011, Tableau Academic has enabled more than 1.9 million students and with software and data skills education and more than 45k instructors with software and teaching resources.

Ashley Koen, Academic Program Marketing Manager (EMEA) at Tableau


Is data viz a skill all managers should know? Is it important for your career?

In the modern digital era, data is an essential component of decision-making at every organization. However, data is simply information and can only be useful when everyone can understand it. Simply put, your data needs to tell a story.

Data visualization enables organization to turn this raw information into a more understandable and aesthetically pleasing visual medium that is easily digestible. Essentially, data visualisation bridges the gap between having lots of data and the ability to understanding it to drive action and decisions.

We are living in an increasingly data-rich world with more and more sources of data being factored in decision-making. The interactive nature of data visualization tools allows users to identify trends across multiple individual sources at the click of a button making it an indispensable tool at the workplace."

Ketan Kundargi - Strategy consultant & Marketing Expert, MBA alumnus at EDHEC and finalist in the 2020 Student Data Viz Challenge


Why teach data visualisation in business schools and universities?

Data visualisation and powerful tools like Tableau are accompanying the data revolution and changing the way we teach data analysis, strategy, finance, technology and marketing. With technology propelling us towards an ever more visual and data-driven style of communication, businesses and organizations need a way to quickly aggregate, analyze and synthesize large amounts of data to help people make better, more informed, and more inspired decisions. The whole world has been using data visualisations to have quick, meaningful updates on the key indicators of the global pandemic, it is a powerful example of how data visualization can impact not only business, but healthcare and public policy. As educators, we need to ensure that students are well prepared for the skills they'll need in the workplace and in the world moving forward. According to McKinsey, higher cognitive skills such as creativity, critical thinking and decision making are among the top skills for 2030, all of these skills are at play when creating data visualizations. Just like Excel revolutionised learning in finance, accounting and statistics in its day, data visualisation tools are changing the way we teach and learn about data.
