Since my childhood, even some of my friends who were good in math were afraid of it or pretending to be afraid of.

Why ?

Because maths are less likely to be understood by the majority of a class. Moreover, the fact that student success in a class is related to its grades, only amplifies the stress and fear of not understanding maths which prevents most people not striving to welcome it. It may sound sad but it occurs that we just tend to ignore “ difficult stuff” because todays societies just keeps us serving our needs in our hands. Even when…

A brief start about color

We consume red strawberries and wait for the white ones to mature. A bar chart containing a red bar might indicate an alert while white bars mean regular activity. Colors give meaning to our context. Colors help us take better decisions. They have both psychological and physiological impacts on us. In the end, how well do we use them?

In this article, we will have a glimpse of what Color Design, Color Theory is, see a few tips for choosing a color scheme, and apply colors to a Widget.

What is data visualization

Files store values. Values are our data. A collection of data is information. Reading raw data stored in a file is possible. But interpreting raw data is impossible by reading it only. That is why we visualize them in an interpretable way.

“The greatest value of a picture is when it forces us to notice what we never expected to see.” -John Tukey

Today, we will drill down into Data visualization.

How did it started

From a historical perspective, data visualization exists since a long time. According to “ Information Dashboard Design: The Effective Visual Communication of Data “…

About context in data visualization

Understanding context in dashboarding is essential and sets you on the path to success when it comes to creating visual content [1].

Today, we will cover this important topic in our journey towards data visualization.

A loopback in its history

Actually, data is visualized since a long time if we don’t consider technologies used for it nowadays. In fact, Physical artefacts such as Mesopotamian clay tokens (5500 BC !), Inca quipus (2600 BC !) and Marshall Islands stick charts (n.d.) can also be considered as visualizing quantitative information [2].

A brief start about Sankey

Diagrams come into play and provide a global view of the information we focus on when we work with data related to industrial systems. Without them, identifying problems may become pretty hard. Sankey diagrams in the industrial sector are used to identify inefficiencies, visualizing energy balance and material flows. They draw attention to the largest flows of the diagram. Today, we are going to explore this helpful diagram by rolling back in its history. Then we will see when and how to apply it to various situations

Everything in life is and should be open to discussion. Sooner or later the truth will be discussed.

As for me, Truth is present in two areas: In science and in speaking.


History shows us that science has always been the art of “Knowing”, showing us the truth of things present everywhere excluding beliefs and intentions. To my knowledge, I dont remember any scientific formula neither research that demonstrates what is beliefs and intentions. Yet nothing proved either that science cant demonstrate these notions.


I will take into consideration every person having the capacity of thinking, thus forming toughts. My…
