A spiral diagram is a type of chart that is used to display hierarchical information. This type of diagram is often used in the fields of software development and project management to illustrate a system's design, a hierarchy, or other information that can be represented as a tree structure.
A spiral diagram starts with the central point and then expands outwards in successive levels or layers. The outermost layer contains the most detailed information. A spiral diagram is a diagram that is composed of a sequence of circles, where the circles are either overlapping or touching. The circles are arranged in a spiral pattern. In most cases, the lines connecting the circles are curved. This type of diagram is often used to illustrate concepts such as hierarchical relationships and time series data.
