What does the bubble diagram of building functional zoning reflect? How to draw?

I went to the wrong place. . . I'd better give you an answer

Architectural bubble diagram is drawn to reflect the division and connection of architectural plane functions, mainly in the design stage.

Different functional spaces make it more reasonable. The drawing method is simple. Write words in the circle, connect the interrelated partitions with straight lines and circle them.

Positioning should conform to the actual situation.
