In today’s big data world, data visualization allows you or decision-makers in any organization or industry to look at analytical reports and comprehend ideas that could otherwise be challenging to understand. Because big data firms are constantly inundated with data, it is essential to streamline how information is presented.
Large data sets present new visualization issues. Therefore, different methods and diagrams are required instead of frequently used visualizations like tables, bar charts, etc. In the best scenario, producing a specific graphic without letting any information slip under the radar is possible.
As Data is increasingly used for crucial management choices, data visualization tools and techniques are crucial in big data to analyze enormous amounts of information and make data-driven decisions. We will provide data visualization techniques and big data visualization tools in this article to help you start simplifying complex Data.
These modern techniques are necessary and a way forward for handling such massive amounts of data.
What is Big Data Visualization?
Businesses typically utilize graphs, bars, and charts to show the relationships between data. They can also utilize various hues, words, and symbols. However, the fundamental issue with this configuration is that it needs to show better massive data or data that contains extremely large numbers. To display numbers and draw links between different types of information, data visualization includes more dynamic, graphical images, including personalization and animation.
The use of more modern visualization methods to show the relationships between data sets is referred to as Big Data Visualization. Applications showing real-time changes and more illustrative images are examples of visualization techniques, which go beyond pie, bar, and other charts. These drawings convey the data in a more visually appealing manner as opposed to using hundreds of rows, columns, and attributes.
Importance of Data Visualization in Big Data
As a part of a fast-growing organization, you see data charts, attend meetings, analyze reports, project targets, check results, etc. Have you ever wondered what goes into making such comprehensive pieces of information that are not only eye-pleasing but also easily understood?
Today, we are exposed to 5 times the amount of information we were in 1986.
- The human brain processes and interprets visuals 60,000 times faster than text.
- 65% of individuals learn best visually.
- In just 13 milliseconds, the human brain can process an image.
If you think these are just numbers, let us understand with an example below:
Which of the below data sets helps you understand the data easily and quickly?
Data set 1
Data Set 2
It indeed has to be the data set 2.
A data visualization expert says that Graphical excellence gives the viewer the most significant number of ideas in the shortest time with the least ink in the smallest space.
This feature of visualizations is what makes them so important in business.
If you are familiar with big data terminology, you have probably heard the term ”massively parallel processing” (MPP), which is most commonly associated with MapReduce technology. It divides data into small units and processes each unit in parallel. We have always used a similar way to process information with our vision. When we look at a visual, our eyes and brain work together to absorb new information and break it down into small chunks. The chunks are then processed in parallel by both the eyes and the brain to find meaning. Let us understand this better with the following example.
Assume we go to the supermarket to buy apples.
Our eyes are drawn to the layout of the supermarket first. At the same time, our brain processes the layout of various sections and instructs the eyes to focus on the fruits section. It accomplishes this by sending signals based on how fruits appear in memory. the eyes then divide the scanned area into sections and scan each section to find the fruits section.the same procedure is followed until we find the apples in the fruits section. This information visualization process is carried out by the eyes and memory working in tandem.
According to the same Wharton School of Business study, data visualizations can cut business meetings by 24%.
- (According to the American Management Association) Managers in organizations that use visual data recovery tools are 28% more likely than those who rely on managed reporting to find timely information.
- Furthermore, 48% of these managers can find the data they require without the assistance of IT personnel.
Different Types of Big Data Visualization.
In the beginning, the most popular visualization method was turning data into a table, bar graph, or pie chart using a Microsoft Excel spreadsheet. Although traditional visualization approaches are still frequently employed, more sophisticated ones are now also available, such as the following:
- Bulleted lists
- Heat maps
- Time Series charts
Here are some additional methods that are in use now.
One of the most fundamental and widely used methods is this one. How variables can alter over time is seen in line charts.
This type of visualization, a line chart variation, shows several values in a time series or a collection of data taken at a series of subsequent, evenly spaced points in time.
This method illustrates the connection between two variables. An X and Y axis with dots to indicate the data points makes up a scatter plot.
This approach uses a nested format to display hierarchical data. Each category’s rectangle size is based on how much of the overall group it makes up. When comparing various elements of a whole data set and there are several categories, treemaps work best.
This method uses a stacked bar graph to show the intricate social history of a population. When attempting to depict a population distribution, it works best.
Widely used Big Data Visualization Tools.
Big Data visualization tools must accommodate several massive data sources and offer immediate analysis. The significant resources for creating a platform for decision-making are
Tableau is a product used in the business intelligence sector that can assist you in converting raw data into an understandable format. You may easily create data visualization with drag-and-drop features and then distribute it to others. Another benefit is the software’s ability to integrate Aible’s artificial intelligence and machine learning into the Tableau interface.

Big Data Visualization Challenges
Big Data Visualization has the potential to be an incredibly potent business tool, but before a company can use it, there are a few important concerns that you must resolve. These consist of the following:
Access to visualization experts:
Many big data visualization solutions are made simple enough for any employee, frequently recommending suitable big data visualization examples for the data sets being analyzed. However, to make the most of some tools, it might be essential to hire a prominent data visualization expert who can choose the finest data sets and visualization types to guarantee that the data is utilized to its fullest potential.
Resources for visualization hardware:
Big Data visualization is fundamentally a computing activity, and to do it rapidly and allow businesses to use real-time data to make choices, it may be necessary to use robust computer hardware, quick storage systems, or even relocate to the cloud. Therefore, big data visualization initiatives are both management and IT projects.
The conclusions that may be drawn from Big Data visualization are as accurate as the data being displayed; if the data is incorrect or out-of-date, the value of any conclusions is in doubt. To manage corporate data, metadata, data sources, and any other types of data, it is necessary to have people and processes in place.
