The Best Data Visualization Tools of 2020

What do you know about data visualization? If you are new to the topic, then be our guest in this article.  We are going to be giving you a gentle introduction into the world of data visualization and discussing some of the popular data visualization tools in the market.

Data Visualization Tools

There is no denying that data has become important more than ever in human history – likewise, is the generation of required data. While data is important to data scientists, researchers, businesses, and government, it needs to be transformed into a format that is understandable and can be communicated clearly and effectively. The need for transforming data into an understandable form led to the birth of data visualization. With data visualization, you can transform complex data, look simple, and easily understand, which helps in the improvement of the decision-making process.

As a data scientist or anyone that deals with data, one of the most important skills you should acquire is the data visualization skills. Data visualization is much more than just representing your data in an understandable format using statistical graphs; you also need to make sure they are visually appealing. This might look difficult at first, but with some data visualization tools in the market, it comes pretty simple. We are going to discuss some of these data visualization tools. Before that, let take a look at data visualization in detail.


What is Data Visualization?

Data Visualization explained

In simple words, data visualization is a technique used by data scientists and analysts to communicate data by encoding it as visual objects (bars, lines, dots, etc.) contained in graphics. It involves representing large datasets into visual graphics,which is done to allow the easy understanding of the complex relationship between and within datasets. Data visualization is often loosely referred to as statistical graphics, information graphics, and even information visualization. The practice is usually the first in data analyst projects.

Data visualization makes use of statistical graphs, bars, charts, plots, and visually appealing graphics to represent data. The practice has been around for a while now – with the Turin Papyrus Map known as the first data visualization piece. This Egyptian map dated back to the 1160 B.C and was used for expressing the distance between quarries. The map also depicts the size of the stone quarried. From this primitive map, data visualization has grown into what we have today.


Why Do We Use Data Visualization?

Just like every other technique used in data science, data analyst makes use of data visualization to achieve some goals. These goals are discussed briefly below.

  • Makes Understanding of Dataset Easy

From the beginning of this writing, we already made mention of this. The major reason why data is visualized is to make it understandable and easy to comprehend. Even if you have the requisite skill, you wouldn’t want to comb through a long spreadsheet of data – and if you do, you will find it difficult trying to make sense of it quickly. What visualization does to your data is that it summarizes it and represent it in easily understood formats.

  • Makes Information Memorable

As humans, we have the capability to memorize visual information in pictorial formats than we can for written information. One of the ways to amplify the information a data portrays is to convert it into a piece of summarized visual information. You will agree with me that data presented in a visualized format is the easiest to memorize.

  • Speeds Up Your Decision-Making Process

When making a data-based decision, data visualization can help speed up the process. However, when using data visualization for a decision-making process, you need to know that if the visualized data is distorted, there is a high chance that you will be making a wrong decision since the visualized data is wrong.

I have a memory of the Highcharts data visualization tool – it was the first data visualization tool I ever used as a Django developer presenting to present data visuals in the user dashboard of a SaaS MVP product I built for fun. I must confess, I love the tool. This tool makes the development of interactive charts easy for web designers. Highcharts has got many of the world’s biggest companies using their charts. However, one downside to this tool that will discourage many from using it is that it is free only for non-commercial usage. If you need it for business-related projects, you’ll need to get a license.

If you can afford the license, then the value you’ll enjoy cannot be overemphasized. With Highcharts, you can create any chart you like, including line, spline, area, areaspline, column, bar, pie, scatter, angular gauges, arearange, area spline range, columnrange, and polar chart. Very important is the fact that Highcharts is compatible with modern browsers.
