Big Data plays a significant role in today’s data-driven industry. With the increasing adoption of big data, there is increasing stress on data visualisation. If you do not know much about data visualisation, then do not worry. By the end of this article, you will have a basic idea of what data visualisation is and which course you should pursue to learn about data visualisation. You should note that data visualisation course has become an essential skill because visualisation helps in the simple representation of the data. Moreover, almost every organisation is becoming heavily dependent on data for its operations, decision-making, and everything else.
Data visualisation helps in interpreting a large amount of data, and it also helps the user in analysing and digesting the data. Data visualisation makes it easy for the user to understand the complex data, which would have been difficult to interpret in the form of raw data. Since it is easy to understand the data visually, data visualisation is gaining a lot of traction. Most of the management business review and management reports have data in the form of graphs and charts, which ensures that the people up in the management do not have to spend a lot of time while understanding the data. By peeling the data set layers, the analyst performing data visualisation can give a new dimension to the data.
So why data visualisation?
You would have already noticed that every organisation is leveraging data visualisation to get access to information faster. This also helps the organisation in recognising the patterns and trends. With the help of this analysis, the future can be predicted very accurately. For example, looking at the past pattern, an associate can do the pattern analysis of Dominos Pizza’s demandon any given day. Based on the forecast, the outlet can plan its inventory and staffing. Using the data to plan the operations would also minimise wastage, and it will ensure that the opportunity is milked in the best possible way. In a way, data visualisation helps in optimising the expenditure and maximising the ROI for the user.
Another example of data visualisation can be the covid-19 dashboards that you see on the web these days. If you look at some of the dashboards, they depict the magnitude of infection on maps using the dots. They also show you the recovery trends in the form of graphs. The graphs and images on these dashboards are also interactive. You can click on a city, and the data for a particular city will be displayed on the screen. All these things have been made possible only via data visualisation.
Courses Available for data visualisation
Data visualisation is a relatively new course, so you would not find diploma or degree courses in this domain. Moreover, data visualisation is a smaller subset of big data or data analytics. In such a case, you will not find a proper degree course for data visualisation. You will come across many certificate programs for data visualisation, and you will also come across a lot of online courses for data visualisation. Another thing to note here is that there are multiple languages used in data visualisation. Knowing any one of those would give you an edge, and it will help you quickly understand the data visualisation. Some examples of these languages used for data visualisation are Tableau, Python, Advanced Excel, R, d3.js and many more.
