Data Visualisation: Your Key to Better Decision Making

In this fast-paced and data driven world, effective decision making is crucial for success in any field. Data visualisation is the saviour of this modern world. It is a powerful tool that can turn huge amounts of difficult-to-understand and complex data into meaningful information. This information can be used for making better and quick decisions. 

Want to know an interesting fact about data visualisation?

Even tho data visualisation is done digitally now, it is believed that Michael Florent Van Langren, a Dutch astronomer, first provided the visual representation of statistical data in 1644, long before digitalisation.


In this article, you will learn why data visualisation is your key to better decision making. You will also understand how it can streamline your processes, improve your understanding, and drive growth.

Understanding Data Visualisation

Before we can fully harness the potential of data visualisation, it’s crucial to understand what it is and why it’s so important. Let’s dive into learning about data visualisation.

What is Data Visualisation?

Data visualisation is the graphic representation of information and data. It converts raw data into charts, graphs, or maps to make the data easier to understand and reveal patterns, outliers, and trends. Some of the widely popular data visualisation tools are Tableau, Microsoft Power BI, and Google Data Studio. These tools offer users an extensive array of visual representation options, thereby helping people to understand data better and make better decisions.

Why is Data Visualisation Important?

This is the age of Big Data. Huge volumes of data are generated every minute. So it has become increasingly challenging to make sense of this data in its raw and numerical form. Data visualisation brings a solution by translating these complex data sets into simple visuals, making data understanding a breeze even for non-data experts. This leads to quicker data analysis, faster decision-making, and improved business outcomes.

The Role of Data Visualisation in Decision Making

So now we have a basic understanding of data visualisation, but how does it impact decision-making? Let’s learn about the important role of data visualisation in business decision-making processes.

Enhanced Data Understanding

Data visualisation allows anyone, irrespective of their technical prowess, to interpret complex data sets. It maps raw data into visual insights, which are easier for the human brain to process and understand. Thus, businesses can make well-informed decisions faster.

Spotting Trends and Patterns

One of the primary advantages of data visualisation is the ability to identify patterns and trends that would be challenging to spot in text-based data. For instance, line graphs can show sales trends over time, and heat maps can show areas with high customer activity. Recognising these patterns helps predict future trends, enabling proactive decision making.

Simplifying Complex Data Sets

With businesses dealing with massive and complex data sets daily, data visualisation offers the perfect solution. By turning complex data into clear, engaging visuals, it simplifies data interpretation and speeds up the decision-making process.

How to Effectively Utilise Data Visualisation for Decision Making

To reap the full benefits of data visualisation, it’s important to know how to use it effectively. In this section, we’ll explore some strategies to harness the full power of data visualisation in your decision-making process.

Identify Your Goals

Before embarking on data visualisation, it’s crucial to identify what you want to achieve. Do you want to understand customer behaviour, track sales trends, or measure product performance? Clear objectives guide your data visualisation process and ensure the insights you gain align with your decision-making needs.

Select Appropriate Visuals

Different visuals serve different purposes. For instance, bar graphs are great for comparing data, while pie charts effectively show proportions. Select the visualisation that best communicates your data and aligns with your objectives.

Ensure Data Quality

The information derived from data visualisation is only as good as the data fed into the system. Ensure you use good quality, accurate, and updated data to avoid misinformed decisions.


Final Thoughts

Data visualisation is not just about beautiful charts and graphs. It’s a game-changer in the realm of decision-making. In a world dominated by data, data visualisation serves as a bridge, translating complex data into understandable and actionable information. It’s a powerful tool that accelerates decision-making, drives operational efficiency, and boosts business growth. 


Embracing data visualisation can be the key to unlocking the full potential of your business decisions. As American statistician W. Edwards Deming once said, “Without data, you’re just another person with an opinion.” So, make your decisions count, use data, visualise it, and let it guide your path to success.
