Data analytics is a process of analyzing raw data to find trends and patterns. However, it involves many different techniques for achieving many other objectives.

Some components of the data analytics process can prove helpful for many initiatives. Analyzing data components will help you determine your company's performance, history, and future.

An approach to Data Science is geared toward finding meaningful correlations between large datasets, while a strategy to Data Analytics is geared toward extracting specific insights from data. It addresses particular questions by Data Science through the use of Data Analytics.

Data visualization represents the data and information in a visual and easily consumable format. It makes data trends, outliers, and patterns more accessible with the help of visual elements such as charts, graphs, and maps.

Data visualization tools and technologies are crucial to analyzing massive amounts of data and making data-driven decisions.

Among its many uses are:

  • Modeling complex events using data
  • Understand phenomena such as mathematical relationships, medical conditions, and weather patterns without having to observe them physically.

In this post, we will look at data visualization definition, data visualization techniques, and the importance of data visualization in depth.

How does Data Visualization help?

Data visualization can play a vital role in any field, whether in business or a career, as it can help in the representation of data more effectively. In business intelligence, the importance of data visualization has witnessed an uptrend because it is responsible for analyzing the raw data, modeling it, and delivering the data to the analyst to interpret the findings and take the appropriate decisions.

Data scientists in advanced analytics are developing machine learning algorithms to create visualizations that are easier to understand and interpret. The use of data visualization enables universal, fast, and effective communication of information.

Using this strategy, a business can identify what areas need improvement, how customer satisfaction is impacted, and where specific products should be sold (to whom and where). With the help of visualized data, a better prediction of sales and future growth is possible. 

Why is it important for modern businesses and data professionals?

Let's examine how data visualization techniques can benefit businesses:

Large and complex data can be absorbed instantly

The information conveyed by large volumes of data can be grasped easily when presented effectively. Creating a visualization from text or numbers is much more difficult than processing ready images due to the series of neural processes required.

Visual representations also make it easier for us to understand the interrelationships between different data points. We internalize things more quickly once we see them.

Therefore, data visualization techniques in data mining create small, easily stored 'packages' of information in the short-term memory of people who will be consuming it. 

These "chunks" are matched according to their hierarchy, color, line weight, scale, and placement. Viewers can understand the data's significance and navigate easily using chunks.

Data-driven decision-making

Meetings with visual data tend to be shorter and more productive than ones held with only text or numbers. Stakeholders can gain a much deeper insight into patterns and trends by displaying data, allowing managers to reach decisions faster.

The benefits of data analytics can be achieved using visualization. Even though your sales staff may not be an expert at interpreting data, you can use the right data visualization techniques to help them understand consumer behavior more deeply. 

With the right tools and training, data visualization allows you to become an expert in technical analytics and creative storytelling.

Engagement with the audience

A good visual presentation allows viewers to relate to data and engage more. The use of images can help drive opinions and actions because they produce emotional responses.

Data allows multiple stakeholders to understand and appreciate insights, communicate, and collaborate on projects. Data is now often presented visually in ways that are easy to understand. 


Getting better agreements 

The exhibition of two components or situations frequently must be analyzed in business. There is a conventional approach to examining both circumstances by analyzing their massive amounts of data. 

Superior methods 

This method allows the representation of two perspectives in a graphical format. By utilizing Google patterns, we can understand information related to top projects or inquiries in a graphical form.  

Data sharing made simple 

Organizations present another correspondence arrangement with the representation of the information. By sharing the visual data instead of the cumbersome information, the data can be more readily absorbed.  

Investigate precisely 

Information perception helps to make patterns more obvious and to draw a better picture of the information. Thus, giving organizations a competitive edge.  

List of Data Visualization techniques and concepts 

Based on these factors, decide which data visualization technique you choose and how their features are configured. Let us discuss the different types of data visualization techniques and concepts applicable:


Charts are the most convenient way to show the evolution of several data sets or one dataset in particular. In a pie chart, components of one whole are displayed as proportions between various elements over time.


Two or more data sets are distributed across a 2D or 3D space using plots to illustrate their relationships with the parameters. There are also different types of plots. Among the most widely used visualizations are scatter plots and bubble plots. Analysts often use box plots to visualize relationships between large quantities of data.


Many industries use maps as a means of displaying data. Using these tools, a geographical map, a building plan, a website layout, etc., can be located. Cartograms, dot distribution maps, and heat maps are the most popular types of map visualization.

Diagrams and matrices

There are usually several data types in one diagram that illustrates complex relationships and links between them. Trees, hierarchies, and multidimensional structures can be used.

When analyzing continuously updated data sets, matrix techniques are used to determine correlations.

Top tools for Data Visualization

Visualizing large data sets can be achieved with various tools, applications, and scripts. The features of most of them overlap, and they have a very basic design.

It is worth noting that some stand out when it comes to creating different types of visualizations or being considerably easier to use than other options.


A free public version of Tableau is available, as well as a desktop app, a server, and a hosted online version. There are hundreds of options for importing data from CSV files to Google Ads, Analytics, and Salesforce data.

Multiple chart formats and mapping capabilities are available as output options. Designers can use color-coded maps to display geographic information in an easier-to-digest format than tables or charts.


Use drag-and-drop functionality to create social media posts, maps, infographics, dashboards, marketing reports, and more.

A variety of export formats are available for finished visualizations, including .PNG, .JPG, .GIF, .PDF, and .HTML. Websites and applications can also incorporate interactive visualizations.


The ChartBlocks API enables data import from "anywhere," including live feeds. It is more difficult to import data into an app without automated modules or extensions than to switch to an app with automated modules and extensions.


Data manipulation with D3.js is possible thanks to this JavaScript library. While some apps allow non-programmers to use D3.js without knowing JS, the library requires at least some JS knowledge.

Google Charts

With Google Charts, you can create interactive charts for displaying online and embedding them into your website. Dynamic data and SVG and HTML5 output are used, so no plugins are required. Salesforce, Google Fusion Tables, and Google Spreadsheets are data sources.

Using charts, you can scatter plots, bar charts, column charts, treemaps, timelines, gauges, histograms, tree maps, pie charts, area charts, timelines, and many other graphs. A simple CSS editor allows you to customize these charts efficiently.

What makes Data Visualization a key skill to have in 2022?

Examples from real-world applications demonstrate data visualization's versatility: 

  • Correlation analysis. It is best to visually compare two variables to determine their relationship and correlation.
  • Examining the network. A network in this context is the entire audience of a particular market. Analyzers can recognize audience clusters by reading their network, including any influencing factors, links, and statistical outliers.
  • Analyzing changes over time. Using data visualization in this way is an essential function of data analysis. Data trends can be visualized and analyzed over time using visualizations.
  • Determination of frequency. Tracking changes is similar to frequency, but frequency measures how frequently a given event occurs.
  • Scheduling timelines. Project leaders can use Gantt charts to show how long each task will take within a project.

Also, many fields benefit from data visualization, including:

  • Research/Data Science: Scientists use data visualization to analyze complex data, recognize patterns, and understand datasets. To complete their tasks, data scientists can use various data visualization tools, including programming languages such as Python. The PG Certificate Program in Business Analytics and Data Science will show you how to accomplish this.
  • The financial sector: A data visualization tool can be useful for investors as it offers the performance of commodities, bonds, and stocks over time.
  • The healthcare industry: The choropleth map shows numeric values in different colors to illustrate other geographical areas. Medical professionals and epidemiologists can use them to track health hazards such as pandemics and heart disease.
  • The logistics industry: Data visualization helps shipping companies determine the best routes for shipping.
  • Politics: Campaign workers and pollsters can determine which regions voted for which candidates.
  • Applied Sciences: Scientists can better understand their experimental data with SciVis or Scientific Visualization.

Use cases of Data Visualization

Trends and spikes in data

Trends or disruptions in the data that require both explanation and remedy are one of the most important tasks of sales and marketing professionals. Comparing this month's blog traffic with last month's is a simple use case.

Goals and results monitoring

Monitoring progress toward a goal. A chart can be made that shows revenue performance against quarterly goals, the percentage of closed won deals, and progress on deal stages in the sales pipeline. 

By monitoring deal performance, sales managers can identify why so many deals don't close and take action to resolve them.

Notification of changes

Sales managers are effectively informed. Managing sales pipelines may be useful for sales managers, who can receive notifications for new deals added by sales reps. The sales manager gets a notification via email. Agents can assist them in closing them by looking at these deals in the CRM.

As society develops sounder strategies for tackling the commercial sector's challenges, we increasingly rely on data. Data analysts are among the most in-demand professionals in today's business world. Those specializing in IT data smithing are skilled at transforming mountains of information into actionable, useful information.
