Explore the Power of Visualisation: Importance, Types, Tools, and More | Business Analytics | Emeritus

Visualisation is a powerful tool to bring data and information to life. Organising and presenting data in charts, graphs, maps, diagrams and other visual formats, can help people understand complex concepts and make informed decisions. 

In this article, we will share the meaning of visualisation and its importance for data analysis and decision-making and its drawbacks.  

What is Visualisation? 

Visualisation is the process of creating graphical representations of data to effectively evaluate, determine trends and make accurate decisions. It helps unlock valuable insights from large datasets and allows organisations to act quickly on those insights.

It enables users to explore data in new ways and gain a deeper understanding of their data. Also, it provides a way for teams to collaborate more quickly, as they can share graphs and charts that convey complex information at a glance.

It is an essential tool for organisations today, as it helps them understand their data quickly and accurately, enabling them to make good and informed decisions about their operations. 

The importance of visualisation cannot be overstated; it provides invaluable insights into how well your organisation is performing and can help inform key strategic decisions.

Importance Of Data Visualisation

In today’s complex data landscape, visualisation is more critical than ever. These tools enable organisations to quickly process vast amounts of data and gain valuable insights into their operations.

Visualisations provide a clear picture of the data that would otherwise be impossible to comprehend in its raw form. It can also help teams analyse large datasets quickly and accurately, identify trends, and make informed decisions about their operations. 

Also, it helps to simplify complex information so that users can understand it at a glance, making it an invaluable tool for organisations across all industries.

They are particularly useful when analysing data from multiple sources or over time as they allow users to see patterns that may not be visible in the raw data. It also helps to highlight outliers, which can provide valuable insights that would otherwise go unnoticed. Visualisations are an essential tool for businesses of all sizes as they allow the teams to analyse data and take action on their findings quickly.

Finally, visualisation is a powerful tool for communication; it helps teams present complex data in a way that is easy to understand and share with others. Visualisations make it easier for stakeholders to understand the implications of their data and make informed decisions about their operations. It also helps organisations communicate their findings more effectively, allowing them to utilise their data’s power better.

It is an integral part of this program as it allows users to identify trends in their data quickly and enables them to take action on those insights.

What are the Types Of Data Visualisation

  • Bar Charts

Bar charts are one of the most popularly used data visualisations. They are easy to interpret and clearly represent data over time or across different categories. Bar charts are great for showing how different elements compare to each other or tracking changes in values over time.

  • Line Graphs

Line graphs are used to display data over time. They help highlight relationships between different variables and can be used to compare data points visually. Line graphs provide a clear visual representation of trends or changes in values over time, making them an effective tool for analysing data.

  • Pie Charts

Pie charts are used to illustrate the relative contributions of each element in a set. They provide a simple visual representation of proportions, making them an ideal tool for displaying data across different categories. Pie charts are particularly useful when comparing the size of other parts to the whole.

  • Scatter Plots

Scatter plots show the relationship between two variables, such as the correlation between sales and customer loyalty. Scatter plots visually represent how two variables are related to each other, making them an effective tool.

  • Heat Maps

Heat maps are used to visually represent the intensity of data values across a range of colours. Heat maps are particularly useful when identifying patterns or correlations between data points.

  • Geographic Visualisations

Geographic visualisations are used to illustrate data in the context of its geographic location. These maps can be used to analyse data such as population density.

  • Treemaps

Treemaps are used to display data that is hierarchical in a rectangular format. They provide an effective way to compare the relative sizes of different elements in a data set.

  • Bubble Charts

Bubble charts are used to display three dimensions of data at once. They commonly compare elements’ relative size and position in a data set.

These are some of the most popular and common types that are used to analyse data. Each type has its advantages and disadvantages and can be used for different purposes. 

What are the Data Visualisation Tools

Data visualisation tools are software applications designed to help users create interactive visualisations of their data. Some popular tools include:

  • Tableau

Tableau is a powerful tool for exploring and analysing large datasets. It allows users to create interactive charts, maps and dashboards that can be used to uncover insights from their data.

  • QlikView

QlikView is another popular tool that provides advanced analytics capabilities such as natural language processing and predictive modelling.

  • Power BI

PowerBI is Microsoft’s suite of Business Intelligence tools that provide an intuitive way to explore and analyse data

  • Microsoft Excel

Finally, Microsoft Excel is a popular spreadsheet program that can be used to create simple Visualisations

  • Plotly and RAWGraphs

Plotly and RAWGraphs are other visualisation tools explicitly designed for creating interactive graphs and charts.

Why is Data Visualisation Important for Any Career?

Data visualisation is becoming increasingly important in any career field as knowledge of data visualisation techniques gives you a competitive edge. Visualisations allow organisations to quickly identify patterns and trends in their data, which can then be used to inform decisions or plans. 

Visualisations are often more engaging than traditional reports and can help create an impactful narrative when presenting data. 

It can make complex datasets easier to interpret using visuals instead of words or text. Ultimately, having a good understanding of visualisation techniques can vastly improve your ability to analyse data more efficiently, helping you become a better asset for any organisation. In short, visualisation skills are essential for anyone looking to use data more effectively in their career.

However, there are a few drawbacks of data visualisation that shouldn’t be neglected. 


In conclusion, a visualisation is an essential tool for data analysis. There are a variety of visualisation techniques available such as heat maps, geographic visualisations and treemaps. Data visualisation tools like PowerBI, Tableau, and QlikView offer powerful features to help users create insight from their data.
