Wassup everybody! Today we will be diving into the sea of Data Visualization. This is a very easily understandable and interesting topic. Let’s say you have 3 years of data on Covid-19 and you want to analyze the pattern. How will you understand and draw insights from this? This is where Data Visualization comes in. Data visualization has the power to unlock insights, communicate complex information effectively, and make data-driven decisions. By mastering this art, you can become a valuable asset in today’s data-driven world. So get ready to witness something fascinating.
What is it?
Data Visualization as the name says is just visualizing the data as graphs or charts to draw insights from it. Let’s say you have the data of a particular stock and want to understand how it has evolved over the last one year and which months it made a profit. You can visualize the data in graphs and understand the pattern.
How to visualize?
There are several ways to visualize data, but the easiest way is to use a business intelligence tool. Imagine having a tool that helps you to organize and visualize the data you have. That is where BI tools come in. The two most popular BI tools are Power BI and Tableau. These tools make visualizing data look very easy.
The other way is to visualize using Python or R. There are several visualization packages available in Python that make our work easier.
How to start learning and become a data visualization expert?
Visualizing data and building dashboards are becoming a very popular job in the IT industry so I would suggest you excel in this field as it is something fun to do and isn’t that complicated.
To learn data visualization, follow the below steps
- start by learning all types of graphs and charts thoroughly.
- Learn different BI tools and learn to visualize using Python and R.
- Build dashboards — A dashboard is collection of visualizations that are presented together on a single screen.
- Learn to draw insights from your visualizations
You can learn all the above steps on YouTube. YouTube is a great platform to learn anything you want for free and make use of this great resource the internet has given us.
If you don’t want to miss out on anything in this field then check out for courses on Udemy/ Coursera which will help you to learn in a structured way. But I won’t recommend that because Data Visualization can be self-taught and it’s not complex at all.
If you want to take it one level up, then earn a certificate by writing an exam like the Microsoft Power BI data analyst certification.
Now let’s look into what data visualization is capable of:
In the above picture, one can easily tell which country reported the most cases and which country has been impacted the most. This is what a dashboard looks like. You can add more features like country-wise oxygen availability, the number of people who are vaccinated, and so on.
This is just a small example and believe me the potential Data Visualization has is huge.
That’s a wrap! I hope you would have found this article informative. The earlier you start, the better it is for you. So, don’t hesitate to dive into the vast sea of data visualization techniques, tools, and concepts.
