Generate resolution-independent circular SVG stroke-dasharray progress meters and radial dials.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Adjust the progress slider (0% to 100%).
Tune circle diameter, stroke width, and gradient stop colors.
Copy the clean SVG code with built-in stroke-dasharray and stroke-dashoffset math.
The circle's circumference (2 * π * r) is assigned to stroke-dasharray, while stroke-dashoffset controls how much of the stroke remains unfilled.
SVG circles start drawing at the 3 o'clock position (right); a -90deg rotation positions the starting point at the top 12 o'clock.
