isIndeterminate

Progress circles can be determinate or indeterminate. Use determinate when progress can be measured against a goal, such as downloading a file. Use indeterminate when the duration or effort is unknown, like reconnecting to a server.

size

Progress circles come in 3 sizes: small, medium (default), or large. These are available to fit various contexts. For example, the small progress circle can be used in place of an icon or in tight spaces, while the large one can be used for full-page loading.

value, min value, max value

The value represents progress within the circle's range, from minimum to maximum. These defaults are 0 and 100 but can be customized. Min and max values don't apply to indeterminate progress circles.

variant

When a progress circle needs to be placed on top of a colored background, use the over background variant. This progress circle uses a static white color regardless of the color theme. Make sure the background offers enough contrast for the progress circle to be legible.
