Thanks to Analytics Vidhya that published my previous article “Data Visualization with React & ECharts” in which I have covered the importance of data visualization and how we visualize the data in React.js using ECharts. Now this time we do the same data visualization plots but with other JavaScript library that is Chart.js. This article helps you to plot & understand some basic visualization of the dummy data with React and Chart.js.

React is an open-source JavaScript library, maintained by Facebook for building user interfaces or UI components.

Chart.js is a free open-source JavaScript library for data visualization, which supports 8 chart types: bar, line, area, pie, bubble, radar, polar, and scatter. …


With the innovation of technologies in the field of Data Engineering, the term Data visualization has significant importance as it is an one of the essential components of Industry 4.0 and 5.0.

Data visualization is about representing data or information in a graph, chart, or other visual format which helps to communicate relationships of complex data with images. The main goals are:

  • quick understanding of the information
  • identify emerging trends/clusters and act quickly based on what we see
  • identify relationships and patterns within digital assets
  • can share our story (results) with others
  • analysis at various levels of detail

Aerial View of Bimmah Sinkhole

Bimmah Sinkhole is the world’s largest sinkhole, was created by a falling star. But on the other hand, Geologists have confirmed that it happened due to erosion. There is a contradiction of locals Omani and Geologists. As a tourist, I was more focused on enjoying the beautiful place, surrounding mountains and fresh water of sinkhole. The location is quite easy through Muscat highway by car because there is no hiking. …


Mathematics have played main role in solving many of the problems. From space to bottom of the earth no field has become successful without the use of brilliant concepts presented by mathematics. It has actually made logical reasoning very easy.

You are passing by a road and you see a bunch of people gathered at a point. What is the first question that pops up in your mind? “Why is there so much crowd?” Yeah?

You are meeting a person for the first time. You both are sitting opposite to one another at a coffee shop table. The person is talking to you, while continuously maintaining eye contact. How do you feel? Of course, good. Because you think the person is paying you attention.

Consider you get a phone call. The speaker says he is from a telephone company and he would like to verify your contact details. He says “Is this 123466?”. If he is incorrect, you immediately say, “No, it’s 565535” just to correct him. You told him your number even when he didn’t know and TADA! If that person has some malicious intent, he would definitely use this contact information against you. So, this is how the human psyche works. Human beings show similar behavior most of the time and social engineers trick them making most of this psyche. …


Usually people believe “the numerical calculations are exact, but graphs are rough” even though it’s completely wrong. Even I was not right about it before learning data analytics.

If you are new in the data science or its sub fields, believe me this is the first step towards the understanding of the importance of Data Visualization along with the statistics result.

Anscombe’s Quartet is the modal example to demonstrate the importance of data visualization which was developed by the statistician Francis Anscombe in 1973 to signify both the importance of plotting data before analyzing it with statistical properties. It comprises of four data-set and each data-set consists of eleven (x,y) points. The basic thing to analyze about these data-sets is that they all share the same descriptive statistics(mean, variance, standard deviation etc) but different graphical representation. …

Just because they are added in your friend list on Facebook, doesn’t mean they qualify to be called your friends. Why? Maybe because you don’t really hang out together or maybe because they didn’t invite you to their wedding. Well! That’s not quite true as the answer is; your brain has limited space for sustaining quality relationships.

This concept was proposed by an anthropologist Robin Dunbar in the 1990’s, who observed the relation between the human brain and the number of connections one can maintain at a particular period of time.

So according to Dunbar, the number of relationships that can be handled by a person is around 150 which is known as Dunbar’s Number. This figure is of course just the rough approximation as it can vary from person to person depending on the type of their personalities, their exposure to the world or gender. …


Data is the new oil. It’s valuable, but if unrefined it cannot really be used. It has to be changed into gas, plastic, chemicals, etc. to create a valuable entity that drives profitable activity; so must data be broken down, analyzed for it to have value. - Clive Humby

Before finding out the truth about this impenetrable event from the past, let me tell you about the Julian calendar that was used back then. Julian calendar proposed by Julius Caesar also consisted of 12 months like the Gregorian calendar established in October 1582 by Pope Gregory XIII that is used today then why the need for a new calendar? …
