Touch-controlled visual guide to Bubble, Insertion, Selection, Shell, Merge, Quick, Heap, and Radix sort. Each algorithm animates the same 48 shuffled values and reports comparisons, moves, and elapsed time. RUN ALL 8 ends with a fair operation-count chart.

Controls: Pause/Resume, Redo, Next, Run All 8, and Algorithm Menu. No Visual reruns the selected algorithm without any animation, touch polling, or intentional delay during the timed section and reports its duration with microsecond-derived precision. The bar animation is rendered through a PSRAM-backed canvas for tear-free updates. Animation work is batched (32 sort operations per candidate frame), the display is capped near 60 FPS, and the independently buffered counter strip updates at 4 Hz so its rapidly changing digits remain readable without flicker. Build with pio run, upload with pio run -t upload.

All Visual runs the eight faster animations and then opens a comparison report. All Fast benchmarks all eight without intermediate drawing and opens the same report with operation-count and measured-time bars.

The PlatformIO platform is pinned to the 54.03.21-2 maintenance release, which includes esptool 5.0.2 and avoids the Click API error present with the original 54.03.21 package on some Windows installations.
