In the world of data science and analytics, data visualisation is one of the biggest requirements today. It combines the qualities of visual storytelling and data analysis. Since the visualisation of data can be used in multiple ways, it is one of those components that cannot be neglected at all in the data analysis industry.
For facilitating this component in analytics, Tableau is one of the most effective tools. It helps you create a visual output from the massive data sets in the spreadsheet. When this data is represented graphically, not only does it have more impact, but it also helps to spot the trends easily in data. It is certainly the biggest business need.
Data visualisation makes it easy to understand the information available in numbers in an excel sheet. So, if you are planning a career, learn more about it.

What is data visualisation?
Data visualisation can be defined as using the raw data, usually numerical data in Excel Spreadsheets, to make a pictorial or graphical representation with the help of the information provided. This technique helps to understand data in a relatively easy manner. After that, you can transfer or present those insights to the parties that require it. In this regard, you must be familiar with some of these visual techniques. These could be charts, maps, graphs, etc. The main objective of this technique is to convert all the large data sets into graphical representations to make them easy to interpret and understand, even for the layman.
What is the Significance of Data Visualisation?
We have already mentioned that data visualisation can convert a large amount of data into an easily understandable visual object. However, there is a deep underlying need for data visualisation techniques. They are:
- The human subconscious can process a lot of information with the help of vision. So, data visualisation can be used to communicate the insights and patterns effectively from the provided data set. If the right colours are used, data can be more impactful. No wonder the ads and movies today are so colourful; they get the message right across to the audience.
- Visualisation of data saves a lot of time while getting the message across to the leaders of an organisation or the stakeholders. It also reduces the margin for error while using these insights since everything has been represented in such a clear and concise manner. This helps in the rapid progression of many industries, especially the ones that are solely dependent on data and graphs.
These two are the underlying reasons why data visualisation is important. If we have to be progress-oriented, then we need to rely more on data visualisation. This is the reason why data analytics has become such an important field in today’s world.
The Considerations We Need to Make for Data Visualisation
Before you dive deep into converting your data into a visual object, make sure you are able to answer the questions that are given below:
- What is the objective of data visualisation?
- What is your target audience?
- What is the message that you want to convey?
- Have you demarcated the KPIs (Key Performance Indicators) of this process?
- Does the historical data representation have the proper implementation while reporting?
How to Bring Data Visualisation to Life?
Thankfully in today’s times, we have multiple data visualisation tools that are making our lives easier and are thus being used heavily in the data science and analytics industry. Some of the popular tools for visualising data are:
- Power BI
- Python and its graphical libraries (NumPy, Pandas, etc.)
You can learn about these tools in a PG in data analytics from a good college/university/institute. The most significant benefit of using these data visualisation tools is that it helps in the development of interactive dashboards, which help us to track, analyse and display data in whichever way we like. This allows us to get many insights from data that even we could not have imagined.
But right now, the immediate need for data visualisation is in setting up an application programming interface (also called an API), which we can integrate for streamlining the data-gathering process from multiple sources. This helps to cut down on a lot of work and reduce the efforts in developing various visualisations of data like charts, tables, graphs, dashboards and infographics.
After learning the various benefits of the visualisation of data, you must be wondering where you could learn data analytics. Do not worry, as you have Imarticus Learning, which has a good data analytics course with placement. Here, you will learn the process of using various data analytics tools and build the best dashboards from the top faculty in the country. Moreover, you will receive the placement assistance needed to find a job in one of the leading firms in the industry.
