Siteswap Diagram
From jugglingpatterns
A siteswap diagram (often called a ladder diagram) is a visual representation of a siteswap pattern. It is often called “ladder diagram”, but as this name chiefly refers to a type of visualization (that "looks like a ladder") than a specific thing being visualized. To avoid ambiguity, this wiki uses the term siteswap diagram.
In such diagrams, each beat of the pattern is shown as a position along a horizontal axis, while throws are represented as arrows connecting the beat when a ball is thrown to the beat when it lands. The beats themselves may be drawn as boxes, circles and contain the numbers indicating the siteswap value.
