Progress Ring Fill

Overview

Draw concentric arcs from a shared origin. Use consistent stroke widths and stagger the fills so the viewer can follow one measure at a time.

Build

1. 01

   Place concentric track circles around a common center.

2. 02

   Rotate the group so each arc starts at twelve o’clock.

3. 03

   Normalize the path length and animate the visible dash from zero to its target proportion.

4. 04

   Stagger the three 1.6-second fills by 250ms. In the five-second study, hold the final illustrative proportions of 82%, 64%, and 43% for comparison.
