It is necessary to understand jQuery as well as AngularJS individually. It is one of the most popular JS library. jQuery is a modular set of a cross-browser method for triggering the elements, choosing elements from the DOM, setting input values and much more. In simple terms, we can say that jQuery is a lightweight JS library that guides developers in clarifying the usage of client-side scripting for web apps using JS. Some key features and benefits of jQuery are
Features of AngularJS:
• Data Binding:
Data Binding provides following benefits to AngularJS Framework:
o No need to write the code which synchronizes the view with the model and vice versa.
o Simplified Programming model
o A decrease in the number of Boilerplate coding.
• Less Coding:
With the help of a conclusive User Interface, 2-way Data Binding & POJO Models, it enables you to form less amount of code in your project with greater capabilities.
• Two-way Data Binding:
The 2-way Data Binding allows auto-synchronization between Model and View components. Data Binding enables you to stores the information and the data in such a way that it doesn't get repeated. Whereas in two-way Data Binding, if there are any changes made to any data, it will reflect the whole model.
• MVVM Architecture:
AngularJS is furnished with MVVM(Model-View-View-Model) Architecture. The HTML template (of a component) is the view & the typescript part is the view model. Connecting the view to the view model is bindings.
• Unit Testing:
Security is the biggest challenge faced by any company worldwide. The whole documentation is provided by the Unit Testing which will always be updated, including the instructions related to your motive of the code & its functional behaviour. The dominant benefit what Unit testing provide is that it forces you to use your code & encounter the defects in your design.

To use charts in Angular, we will use the chart.js library to construct the charts. We will fake the backend server for data and display it on charts.
