By default, progress circular uses the applications primary color.

Just as with the progress circular component, progress linear has an indeterminate state.

The progress linear component can have a determinate state modified by mat-progress-bar

For situations where the user wants to indicate pre-loading (until the loading can actually be made), use the query indicator.

A buffer state represents two values simultaneously. The primary value is controlled by the model, whereas the buffer is controlled by the buffer-value prop.

An indeterminate progress circular animates forever.

The progress origin can be rotated.
