Why did I created these Chart JS video tutorials?
Have you ever used Excel where charts appear almost magically with a click on a button. You notice if you look at a chart or graph you can absorb information within seconds which would take you minutes if it is a table with data.

“A picture is worth a thousand words”

We all know that pictures and colors spark the mind. However, if you try to draw or code a 📊 bar chart or a 📈 line chart, or any type of chart in a Javascript library it is a big challenge. The documentation makes it hard and the it is very hard to work with a canvas tag.

Ancient Egypt used hieroglyphs in their writing system. Which was both logical and creative at the same time. And this is why I love charts as well. A chart is the closes to translating logic into visuals. Making the chart interactive is the best way to communicate your message to others.

If we know about this why is coding charts so complicated?

Because computer programming language is based on 100% logic. This is why when you look at Chart.JS, D3.JS, Chartist and other chart libraries in JS you will need to basically explain in logic to a computer what to make visual.

How and where can I help?

My goal and focus is on creating easy to understand Chart.JS videos so you can start using Chart JS in all your website endeavors making Chart.JS a topnotch and leading JS library for the years to come. Just like any programming library once more people use Chart JS it will attract more people to contribute and grow.
