What is Data Visualization?
Data Visualization is presentation of anything. We can first take example from our life itself to understand it properly. Assume you are going to get delivery of your new car. After reaching delivery center you didn't get any welcome from staff and you were shocked to see that your car is not cleaned properly as well. It is dirty in mud and tyres are also too dirty in dust and mud is everywhere. Here in this scenario we can say that presentation/visualization is not good. How will you feel after facing this situation? You may not take delivery and cancel your order, no matter how good car is. If you take delivery then you will not be happy as you were at the time of leaving your home to delivery center.
On the other hand if everybody were there at reception to welcome you and your car was shining like star then you will be happiest person of earth and you would like to take some selfie and post those on social networking site to show your happiness. In this scenario, game is all about visualization.
Same way when you are working in any organization then you will be working on data which you will be getting from client in the format of Excel, CSV, Notepad, Database. Being master of data processing, you will analyze data as per business requirement but what you need to do after analyzing data? You need to share your findings with your client or business user. Business user are management guys and they do not have programming or data processing software knowledge. They only understand data in form of charts, pivots. Presenting data in format of charts and pivots is called Data Visualization in business language. Data Visualized in proper way is easy to understand and business user can take corrective and proactive business decision easily.
Why do we need Data Visualization (Tableau / Power BI)?
We have discussed what is Data Visualization in previous section. Now question comes why we need to do Data Visualization. Simple answer to this is because after analyzing data in SAS, R, Python, Excel or any other software you need to present result back to client so that they can take business decision as per business requirement. You will be processing data in data processing softwares which business users do not understand. Therefore you need to present data in format which is easy to understand quickly without being confused.
What we need to do in Data Visualization (Tableau / Power BI)?
Whenever you will work in any project, you will start getting requirements from client about what they want you to analyze. Now you will have to present data in visual format using charts/pivots whatever suits requirement and share that back to client. The work which we deliver to client in Data Visualization is called Dashboard.
What technology we need to learn for Data Visualization (Tableau / Power BI)?
World is growing faster and there are various technologies available as a Data Visualization solution. Excel is one of required solutions for Data Visualization. We also have Tableau, Power BI, QlikSense, QlikView, D3.js, Spotfire etc available in market as Data Visualization software solution. Tableau and Power BI are two of all mostly used solutions as per current market demand. Tableau is market leader and Power BI is following it back to back. Then others are also following queue.
You can choose to learn Tableau or Power BI as per your choice. You can watch our below video where we have compared both.
What salary you may get after learning Data Visualization (Tableau / Power BI)?
Data Visualization employees are highly paid in all organizations. Data Visualization salaries starts from 4 LPA in India. I would say that there are various countries and I cannot give salaries for all countries but salary is quite high in Data Visualization job. You can search job in Google as per your country and you will get answer as attractive salary package.
What is future of Data Visualization (Tableau / Power BI)?
Your future is secured in Data Visualization but time to time you will have to update yourself as per business and organization requirement. Tableau and Power BI are not going anywhere at least 10 years from now. But suppose if some new good technology comes in future then you must learn that too. Data Visualization is concept and it is performed using softwares like Excel, Tableau and Power BI right now. My recommendation is be ready to update yourself if you want your future to be secured. We can take one example from our life as well. Now world has changed and we have smartphone with us. We are not using those old age kind of phones, same way with time, technology also keep improving itself and we also need to keep improving ourself.
Can non technical background student learn Data Visualization (Tableau / Power BI)?
Answer to this question is big YES. Most of Data Visualization solutions are drag and drop/ GUI based software solutions therefore using those is quite easy and anybody can build any dashboard in those softwares easily. By any chance if you are interested to learn D3.js as Data Visualization solution then let me tell you that D3.js is not drag and drop or GUI based solution therefore building dashboard in D3.js will be typical if you are not having programming knowledge. Definately you can learn it and start building any dashboard as per requirement.
What educational background required for Data Visualization (Tableau / Power BI)?
If you are graduate then you can start with Data Visualization job after learning Data Visualization softwares.
Do we need programming knowledge to learn Data Visualization (Tableau / Power BI)?
GUI based Data Visualization software does not require any programming knowledge whereas you need to have knowledge of writing advance versions of functions/formulas like Calculated fields in Tableau and DAX in Power BI.
You need to learn other software solutions as well to get Data Visualization job because before preparing any dashboard, you need to processing or manipulate your data in SAS, R, Python or SQL. SQL is easier to learn when comparing with SAS, R, Python and SQL but you cannot crack complex business problems using SQL only. Therefore you must have knowledge of one from SAS, R and Python.
Which companies hire for Data Visualization (Tableau / Power BI)?
Simple answer to this question is All companies which are looking to make profit, will hire you. There is not a even single company in world which is not looking for profit.
How long it take to become Data Visualization Expert (Tableau / Power BI)?
Any visualization software solution can be learnt within one month if your instructor is teaching honestly and you are dedicated to learn. What do I mean by honestly here? Everybody will write course name such as Tableau Zero to Hero or Power BI master in 10 Days but it does not mean they are going to teach you what companies are looking for. You do not have any knowledge about software. You will think that you have learnt everything whatever your instructor have taught you. I mean to say that nobody can make you Zero to Hero in 5 hours or 10 hours free of cost. Think logically
Do we need certificate?
Certificate will definately help you and all institutes provide certificate therefore my motive to discuss this point is please do not run behind certificate. You must focus on learning best because knowledge is the only one thing which will help you to grab job. Having certificate is not guarantee to get job.
From where you should learn Data Visualization (Tableau / Power BI)?
You can learn from any where but you need to decide institue or source of learning based on few points. Do not run behind free course because nobody is going to teach you actual thing free of cost. Everybody is working for money. You can think about yourself. Why you are looking for to learn Data Visualization? Can you work free of cost in any company? Then relate this point to instructor, why would somebody will teach you free. If you are looking to grab job then you need to choose paid courses because Instructor will give you right path and you will be able to learn Data Visualization without wasting time. Free courses are created for views only with basic knowledge and basic knowledge never helps to crack business problems of companies.
You should talk to instructor and try to take free demo class and compare demo of 5 to 10 institutes for both Tableau and Power BI to understand explanation method of instructor. Check if fee is feasible for you.
Do not run behind 100% job promise because all institutes write 100% Job assistance and we as student think that it is 100% Job guarantee. Assistance means help, which means institute will help 100% to grab job like telling you about job opening, help to prepare resume etc. but you will have to crack interview at your own. Therefore you must focus on learning best.
Final Note: Data Visualization is finishing line of any project. No matter how fast you ran but you will not win if you do not put your leg on finishing line. Same way no matter how good you have processed or manipulated your data, no matter how good Machine Learning model you have built, your work is wasted without good Data Visualization therefore you must be good Data Visualizer as well. You must have knowledge at least any one of Tableau or Power BI. We have more options avaiable in market but these are mostly used and asked by organizations.
