The videos explains the chart js documentation in a more visual and easy to understand way. You can follow along with the code and quickly grasp how it works. We cover the code in chart js but also what truly happens and why something happens when we write a line of code. This fundamental understanding gives clarity to you as a developer in chartjs. In short it is the Chart JS video documentation.
