Diagrams are great, because they are a very simple and extremely efficient way to intelligibly represent even the most complex ideas. But drawing diagrams can also be very complicated, simply because most diagramming softwares require you to draw.

With Lovely Charts’s extremely simple and intuitive drag’n drop drawing mechanism, you’ll be able to focus on what really matters. You won’t have to draw boxes and arrows, you won’t have to worry about what symbol to use.
