What is Data Visualization?

Which image gives you a better idea of the data represented? Most people would get a clear view of the second image. This is something data visualization is all about. It is merely the representation of data in graphical form.




What is Data Visualization

“There is magic in graphs. The profile of a curve reveals in a flash a whole situation — the life history of an epidemic, a panic, or an era of prosperity. The curve informs the mind, awakens the imagination, convinces.” – Henry D. Hubbard

Whenever you are given a lot of information, you may be converting it into tabular form to get an easy understanding. Data is essential only when you can get insights from it, and else it is redundant.

Consider the two images shown below:

Which image gives you a better idea of the data represented? Most people would get a clear view of the second image. This is something data visualization is all about. It is merely the representation of data in graphical form.

If we have a small data set, understanding it in a tabular form is secure. But if the amount of data is enormous, assuming it becomes too complicated, hence the need to visualize it. By using representations like charts, graphs, or maps, you get an accessible way to understand the trends and patterns in the data.

It is a personal tendency to get attracted to colors and patterns rather than standard text. The human brain is quick to differentiate between green and red, or square and circle. Visual effects create a better impression on our minds.

For example, a process explained through animations is understood quicker compared to that described in a book. This is why data visualization is essential for people as well as businesses.

Today, companies believe in making data-driven decisions as it allows them to meet customer needs and develop best-in-class products.

Rising technologies like Artificial Intelligence, Machine Learning, and Data Analytics have made data visualization more critical than ever.

Data visualization helps in converting trillions of rows of data generated into a form that is easy to understand, and through which we can find growth patterns, profit/loss, Return on Investment (ROI), total sales, and a lot more information that can be conveyed to stakeholders.

Read on to know why data visualization is essential, its types, data visualization tools, and why taking Tableau course training should be your next career move.

1. Importance of Data Visualization

Whether you are working in retail, banking and finance, marketing, sales, education, eCommerce, or even in governmental organizations, data visualization is crucial to communicate information clearly and efficiently. It is also one of the steps of the process of data science.

The data science process involves collecting data, processing, and modeling it, and after that, the data should be visualized to draw conclusions and make better decisions.

Data Visualization has witnessed continuous growth over the past few years. The global data visualization market that was worth USD 4.51 billion in 2017 is expected to reach USD 7.76 billion by 2023, at a Compound Annual Growth Rate (CAGR) of 9.47 percent over the forecast period of 2018 to 2023.

The driving factor of data visualization is the fact that there is an increasing emphasis on measuring the performance of every operation to check the daily progress.

2. Here are some of the points depicting the importance of data visualization:

Traditional descriptive statistics are not capable of giving insights from the massive amount of data that we generate today. It is a data visualization that gives improved insights.

Going through spreadsheets or reports is a tedious task which delays decision-making. Data visualization allows for quicker decisions by presenting complex data through interactive dashboards and graphs.

Data visualization can also be used to identify areas that need improvement, understand which factors affect consumer behavior, predict sales volume, and more.

Companies today are focusing more on big data and data analysis related projects, and data scientists take the help of data visualization to ensure that the process is giving desired results.
Data visualization also gives an increased understanding of the next steps to be taken to improve the processes.

3. Types of Data Visualizations

Data can be visualized in various ways:

  • Charts
  • Tables
  • Maps
  • Infographics
  • Graphs
  • Dashboards

These mentioned ways again have sub-types like line charts, pie charts, treemaps, histograms, bullet graphs, dot distribution maps, heat maps, population pyramids, Gantt charts, and more.

4. Data Visualization Tools

Data scientists can achieve data visualization through many powerful tools like:

  • Tableau
  • Qlikview
  • Plotly
  • Power BI
  • Datawrapper
  • Highcharts
  • Sisense

Tableau is one of the numerous robust data visualization tools which can prove to be the most secure and flexible end-to-end analytics platform for your data. Here are the products that it offers:

Artificial Intelligence (AI)

AI in Education: Importance and Benefits of Using It

The potential is enormous, especially when artificial intelligence or simple AI is involved. It mimics the brain of the human and provides instant results and calculations.




Artificial Intelligence App Development Trends

Technology is widely used in merely all spheres of human activity. It serves people in a variety of ways. It simplifies many processes, provides tips, speeds up any function, enhances productivity, and so on. The potential is enormous, especially when artificial intelligence or simple AI is involved. It mimics the brain of the human and provides instant results and calculations. Therefore, it is no surprise this technology is used in education with huge benefits.

Lauren Bradshaw is a famous writer, professional researcher, and blogger employed at a leading essay writing service called CustomWritings. She covers many topics related to students, education, and technology. She has shared one exciting thought, and we want to provide it here:

“The use of artificial intelligence will sufficiently ease the life of students in many ways. Students will comprehend and learn new materials very fast. Smart technology will help to develop skills fast, and they will be applied correctly. The perspectives are enormous.” We understand the point of view of Lauren, because we think the same way. Our helpful blog post casts more light on the benefits and importance of AI in education.

1. Automation

One of the essential benefits of AI is the automation of merely all processes. It saves precious time and energy. AI can help students, as well as teachers and professors. For example, students can create interactive schedules that reflect all the tasks and grades they have. Thus, youngsters will know what should be done and how good their score is. AI will calculate the odds, and students will know if any adjustments and improvements are required.

Teachers and professors do not have to spend heaps of time checking the progress of their students. An intelligent program will take into account the grades of all students and will provide the average rates. Educators will not spend their energy doing that and will have more time to heed the students who need their support more.

2. Big Data Collection

Artificial intelligence may help learners and educators in finding the correct information. It works fast and ensures the desired results. Every time you place an online request, AI registers it and saves it in your browser’s history. This function helps to speed up the process of searching and makes it more accurate. After it gathers enough facts from the requests of all users, you receive instant targeted results. For example, you may write an “essay,” and the browser will provide you with all related products:

Artificial Intelligence (AI)

  • How to write an essay;
  • Essay writing structure;
  • Essay outline;
  • How to write an introduction to an essay;
  • How to research an article, etc.

It hugely saves time, and users receive instant search options that are relevant for them. AI may provide recommendations of information sources that can be helpful for students. These are:

  • Learning courses and programs;
  • Educational websites;

3. Assistance for Disabled Students

As we all know, some students have specific disabilities. They appeared because of accidents, traumas, or genetic peculiarities. Students have problems with talking, walking, or writing. AI can overcome most of those complications.

Let’s review a few typical situations. A student has problems with gripping. He cannot hold the pen firmly, and it is impossible to understand what he writes. Thanks to special digital writing tools and AI, this issue can be successfully solved. A student should take a special pen and write with it on the screen. AI will analyze what is written and will type it.

Another example is related to students with speaking issues. They may not be able to pronounce all the words. Thus, a specific AI technology can speak instead of them using an intelligent, sensitive algorithm. It can identify the quietest sounds and pronounce them instead of a student. Steven Hawking used to utilize this unique technology. Mind that he could not speak and even move.

4. Interactive Assistants

AI software is brilliant and can become the most effective helper of students. It is used in various learning tools and helps to improve skills and avoid mistakes. The most widely used learning apps based on artificial intelligence are:

  • Grammar checkers. These intelligent apps scan the text and underline grammar, punctuation, and spelling mistakes. They also show how to correct those mistakes.
  • Editors. Thanks to online editors, students receive editing tips to improve the readability of their texts.
  • Topic generators. If you have problems with choosing a topic, topic generators will help you. AI proposes the most relevant ideas after you specify at least one keyword.
  • Organizers. An intelligent organizer may become your assistant. It will schedule and adjust your routine. Thanks to its assistance, you’ll be able to control time and optimize your work.

5. Virtual Reality

Artificial intelligence allows using virtual reality or, shortly, VR. AI will create unique environments for students according to their needs and the goals of their educators. For example, nobody can travel back in time to observe Ancient Greece or Rome or travel to the time when dinosaurs lived. Thanks to a special algorithm, AI provides this opportunity.

They should only put on special glasses and headsets to feel the virtual world as accurate. Such use of artificial intelligence makes lessons more attractive and provides more details necessary for adequate comprehension. It encourages students to attend such classes and do their best to succeed in learning.

The Bottom Line

As you can see, the potential of artificial intelligence in education is beneficial for educators and learners. It assists fast and precisely. Students can find the required data, optimize their schedule, improve learning skills, get brilliant prompts, and save heaps of precious time. It is only necessary to find the right software, optimize, and use it correctly. The positive results will appear almost in a blink of an eye. AI has the potential we cannot ignore. It should be used wisely.
