Onion Diagram How to Draw?

Create a new flowchart, check the categories of graphic symbols needed in the graphic area under 'More Shapes'.

Drag the circular element from the left side of the graphic area to the canvas, then drag the text box element onto the circle to name the central theme.

Continue dragging circular elements to the canvas, enlarge the size of the middle and outermost circles to make them gradually larger by hierarchy, and add related dimensions and external environment elements.

Enhance the logical relationship between layers through colors, lines, or icons.

After the onion diagram is drawn, it can be downloaded or shared with others.
