From 659ba233b656e7015c614eb5ac06b3821c8e4ebc Mon Sep 17 00:00:00 2001 From: sachinlala Date: Sun, 21 Sep 2025 04:51:28 +0530 Subject: [PATCH 23/28] Redesign radix sort visualization with clean color-coded approach MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Removed bulky bucket containers (B0, B1, B2, etc.) that were cluttering the UI - Replaced with clean color-coded cell animations similar to bucket sort fix: * Elements change color based on their extracted digit (0-9) * 10 distinct colors for digits 0-9 in a compact color legend * Smooth scaling and rotation animations during distribution * Color reveal animation when elements are grouped by digit - Updated CSS styles: * Replaced radix-buckets-container with radix-color-guide * Clean grid layout for digit color legend (5 cols desktop, 3 mobile, 2 small) * New animation states: digit-colored, pass-complete with smooth transitions * Enhanced dark mode support for color guide and legend * Mobile responsive adjustments for color grid layout - Improved animation flow: * Extract โ†’ Color by digit โ†’ Distribute (scaling) โ†’ Collect โ†’ Pass complete * Visual focus on current digit position (ones, tens, hundreds, etc.) * Cleaner legend with emoji indicators for each phase * Reset function properly clears colors and animations - Educational benefits: * More intuitive visualization showing digit-based grouping * Less visual noise, easier to follow the sorting process * Color legend helps understand which digit values map to which colors * Maintains digit extraction highlighting with red pulsing display This fixes the same UX issue as bucket sort where bulky labeled containers were replaced with elegant color-coded animations for better clarity. --- algorithms-js/assets/css/styles.css | 206 ++++++++---------- .../src/sort/radix-sort/radix-sort.config.js | 138 ++++++------ 2 files changed, 166 insertions(+), 178 deletions(-) diff --git a/algorithms-js/assets/css/styles.css b/algorithms-js/assets/css/styles.css index 7dab48cd..b686f119 100644 --- a/algorithms-js/assets/css/styles.css +++ b/algorithms-js/assets/css/styles.css @@ -2340,116 +2340,93 @@ body.dark-mode .viz-cell.complete { font-size: 18px;

charset=UTF-8 Content-Transfer-Encoding: 8bit - Replaced vertical list layout with sleek horizontal row of colored circles - New design features: * Compact header 'Digit Colors:' instead of full title * 10 colored circles (24px) with digit numbers inside (0-9) * Single horizontal row with center alignment and flex wrap * Hover effects: circles scale up 1.15x with shadow on hover * Tooltips showing 'Digit X - #colorcode' on hover - CSS improvements: * Removed old grid layout and color boxes * New .radix-color-row with flexbox center alignment * Interactive .radix-color-circle with hover animations * Reduced padding and cleaner visual design * Enhanced dark mode with proper circle border colors - Mobile responsive: * Circles scale down: 24px โ†’ 22px โ†’ 20px on smaller screens * Font sizes adjust appropriately for digit labels * Maintains horizontal layout across all screen sizes * Flex wrap ensures circles don't overflow on narrow screens This transforms the cluttered vertical list into an elegant, compact horizontal bar of colored circles that's much more space-efficient and visually appealing.
