I used Draw.io for creating an EER diagram along with one other teammate. We both collaborated on this project and Draw.io was seamlessly updating the diagram in real-time, which really grabbed my attention and something that I found very helpful. Draw.io is a great tool for collaborative whiteboard to create charts, diagrams, and other such artistic things. Ease of integration definitely helped me in choosing Draw.io. Also I use it very frequently almost every week. Its very easy to use which makes it better than other competitors.

Work from anywhere/any computer and just open draw.io on browser and start working!! Save ur diagrams locally, on google drive or on other cloud options

it connetcs to my cloud services, it is available to use offline, lightweight and easy to use
