To visualise is sometimes a better way of expression than words. In prehistoric times, when man’s language was still underdeveloped, he used the walls of the caves to etch things that fascinated him. You can say that data visualisation began there: with his stories about the stars he saw. From the cave to the paper and to the digital screen, data visualisation has come a long way.
In this day and age where huge amounts of data are churned out every day, it is important to have graphical data representation that can be concise and precise to deliver the information to the viewer. Without this the world with all its businesses, science and technology will be back in the iron age, because it is near impossible to fathom a world without data visualisation.
What is Data Visualisation?
It is an interdisciplinary field combining arts (graphical representation) and science (statistics, technology). The idea is to effectively communicate vast amounts of data (e.g.: time series) in the clearest way possible. Every industry requires data visualisation, where their data (sales, profits, losses, consumer percentage, over the years, population, diseases, literacy rate, etc.) is mapped from original data (in numbers) to a graphic form (e.g.: lines or points in a chart). From the mapping, you will be able to comprehend and analyse complex data effectively. (showing comparisons, causality, patterns, etc.)
This discipline thus has roots in statistics as well as in arts as it requires great design skills. Data visualization could be in the form of plots, statistical graphics, information graphics and other tools.
Who can pursue Data Visualisation courses?
- You are great with numbers (mathematics field, perhaps)
- You are an artist at heart and knows how to convey complex stuff in an attractive way.
- You are already a professional (IT field, research, academics, business, healthcare, etc. ) and every field has factors that are measurable and now requires the skills of data visualisation to convey them effectively. This helps your work/business.
- You want to learn all the ropes of this trade and are already a skilled programmer, so you can go the extra mile and learn the ins and outs, rather than skim the surface.
Essentially, it is about becoming a great storyteller with the right technical skills. It is the future. There are many data visualisation courses which are right for you.
Eligibility Criteria for Data Visualisation courses
Note: Please note that, as mentioned before, anyone can learn the basics by skimming the surface. Even if you don’t have a mathematical and computer related background, you can still learn the basic features, so you can represent data. (e.g.: maps, charts, bar graphs, etc.)
But to go deeper into this field, you will require expertise in mathematics, statistics, programming, etc. This will enable you to bag roles such as Data Analyst, Data Scientist, Data Visualization Engineer, Business Intelligence Analyst, etc.
For all the above, you will require (10 +2) qualification with a minimum passing percentage. Depending on the course and the institute, the admission criteria could be merit based or through entrance exams.
But you can learn more nuances by taking online Data Visualisation courses

So take some of the best data visualisation courses to convey information better.
Q: Are there any online Data Visualisation courses?
A: Yes there are many online Data Visualisation courses offered by top institutes and educational companies which are recognised worldwide. However to take on specific roles such as data scientists, data visualisation specialists, etc. you will need to take the relevant degrees.
Q: What is the duration of Data Visualisation courses?
A: Most UG courses, (BCA, B.Sc., B.Tech, etc.) take 3-4 years to complete. PG courses will take 2 years to complete. Most Data visualisation certification courses can be completed within a few months.
Q: What is the future of Data Visualisation courses?
A: With more data being churned out than ever, there is going to be even more high demand for data visualisation. This is not just for professionals in data science and visualisation. Everyone else will also at some point require some skills to represent their ideas, datas, etc. to their colleagues, clients, etc. Thus taking even smaller online data visualisation courses can make a huge impact in the career.
Q: What are the different fee structures for Data Visualisation courses?
A: Most diplomas, UG and PG courses can cost from a few lakhs to astronomical heights depending on your course institute as well as the sector (public or private). Online data visualisation courses range from free to paid courses and the latter cost around a few thousand rupees to well below 1 lakh.
Q: Is it difficult to learn data visualisation courses?
A: That would depend on the extent to which you want to pursue the skill. Careers in data visualisation, data science, data analysis, etc. require mathematical and advanced technical skills. But you only need to know basic visualisation skills to make attractive data visualisations to convey something in your workplace.
