Data visualization is one of the processes in the data science process that asserts that data must be visualized once it has been collected, processed, and modeled in order for conclusions to be drawn. Data visualization is also part of the larger data presentation architecture (DPA) discipline, which seeks to discover, retrieve, modify, format, and convey data in the most effective manner feasible.

Data visualization is essential in practically every profession. Teachers can use it to display student exam results, computer scientists can use it to enhance artificial intelligence (AI), and executives can use it to share information with stakeholders. It is also very important in large data projects. Businesses required a way to rapidly and easily acquire an overview of their data as they amassed large amounts of data during the early years of the big data trend. Visualization software was a natural fit.

For similar reasons, visualization is essential in advanced analytics. When a data scientist is developing complex predictive analytics or machine learning (ML) algorithms, it is critical to display the outputs in order to monitor results and confirm that models are working as expected. This is due to the fact that representations of complex algorithms are often easier to understand than numerical outputs.

What is the significance of data visualization?

Data visualization is a rapid and effective approach to present information in a universal fashion through the use of visual data. The method can also assist firms in determining which aspects influence client behavior, identifying areas that need to be addressed or given more attention, making data more remembered for stakeholders, understanding when and where to deploy specific products, and forecasting sales volumes.

The following are some additional advantages of data visualization:

  • Ability to absorb information quickly, enhance understanding, and make decisions more swiftly.
  • A better knowledge of the next measures needed to strengthen the organization.
  • A better capacity to keep the audience’s attention with material that they can understand
  • A simple distribution of information that increases the potential for everyone concerned to give insights.
  • Data scientists are no longer required since data is more accessible and intelligible
  • An enhanced ability to move fast on findings and, as a result, achieve success with more speed and fewer errors

Big data and data visualization

The growing popularity of big data and data analysis initiatives has enhanced the need of visualization more than ever. Machine learning is rapidly being used by businesses to collect vast volumes of data that can be difficult and time-consuming to sort through, interpret, and explain. Visualization can help to accelerate this process and deliver facts to business owners and stakeholders in ways that they can grasp.

Big data visualization frequently extends beyond traditional visualization approaches such as pie charts, histograms, and business graphs. It instead employs more complicated visuals, such as heat maps and fever charts. Big data visualization necessitates the use of powerful computer systems to collect raw data, process it, and convert it into graphical representations that humans can utilize to swiftly draw conclusions.

While big data visualization can be advantageous, it can also have significant drawbacks for businesses.

A visualization specialist must be employed to get the most out of big data visualization technologies. This specialist must be able to determine the appropriate data sets and visualization techniques in order to ensure that firms make the best use of their data.

Because big data visualization necessitates strong computer hardware, efficient storage systems, and possibly a shift to the cloud, IT and management are frequently involved in big data visualization initiatives.

Big data visualization can only deliver insights that are as accurate as the data being shown. As a result, having people and systems in place to oversee and control the quality of company data, metadata, and data sources is critical.

Data visualization examples

The most frequent visualization strategy in the early days was to use a Microsoft Excel spreadsheet to translate the information into a table, bar graph, or pie chart. While basic visualization approaches are still widely used, more complex techniques.

  1. Line graphs: This is one of the most fundamental and often utilized procedures. Line graphs show how variables change over time.
  2. Area graphs: This is a line chart variation that depicts numerous values in a time series – or a succession of data collected at consecutive, equally spaced periods in time.
  3. ER diagram tool: A high-level conceptual data modeling diagram is an ER diagram. It aids in methodically analyzing and determining the data requirements necessary for successful database design.
  4. Plots with scatter: This method demonstrates the link between two variables. A scatter plot has an x- and y-axis with dots representing data points.
  5. Treemaps: This method displays nested hierarchical data. Each category’s rectangle size is proportionate to its percentage of the total. Treemaps work well when there are several categories and the purpose is to compare different aspects of a whole.

Use cases for data visualization that are common

Sales and marketing.

According to Magna research, 50% of all worldwide advertising dollars will be spent online by 2020. As a result, marketing teams must pay close attention to their web traffic sources and the money generated by their web domains. Data visualization makes it simple to see traffic trends as a result of marketing efforts across time.


A geographic map that shows which party each state or district voted for is a typical usage of data visualization in politics.


Choropleth maps are commonly used by healthcare practitioners to illustrate crucial health data. A choropleth map depicts geographical areas or regions that have been color-coded in relation to a numeric value. Professionals can use choropleth maps to see how a variable, such as the mortality rate of heart disease, varies throughout various territory.


Scientific visualization, abbreviated as SciVis, enables scientists and researchers to get more insight from their experimental data than ever before.


When deciding whether to buy or sell an asset, finance professionals must monitor the performance of their investment decisions. Candlestick charts are trading tools that aid finance professionals in analyzing price movements over time by displaying crucial information such as securities, derivatives, currencies, stocks, bonds, and commodities. Data analysts and finance experts can spot trends by evaluating how the pricing has changed over time.


Visualization technologies can help transport businesses discover the optimal worldwide shipping routes.

Researchers and data scientists

Data scientists often create visualizations for their own use or to disseminate information to a small group of people. The visual representations are created utilizing visualization packages from the programming languages and tools of choice. Data scientists and researchers typically employ open source programming languages, such as Python, or proprietary data analysis tools. These data scientists and researchers use data visualization to better analyze data sets and find patterns and trends that might otherwise go unreported.

The Visualization of Data Science

Understanding how humans gather and interpret information is the foundation of data visualization science. Amos Tversky and Daniel Kahn worked on research that outlined two distinct ways for acquiring and analyzing information.
