Figma is a popular tool for brainstorming and wireframing. It is a whiteboard application that allows us to collaboratively brainstorm ideas. It also lets us create interactive prototypes of a software system without coding, allowing us to create and iterate on design ideas quickly. To work on design activities in class and for your assignments, you need to create an account for Figma.
See the following YouTube video playlist provides a nice introduction on how to create and use design systems. Take a look if you intend to create a design system for your project!
