🐛 What Was Fixed

Before:

const Layout = require('algorithm-visualizer').Layout;
Layout.setRoot(new Layout.VerticalLayout());  // ❌ Error!
Layout.add(logger);

After:

const { Array1DTracer, LogTracer } = require("algorithm-visualizer");
const logger = new LogTracer("Operation Log");  // ✅ Works!
const cacheTracer = new Array1DTracer("...");

Changes:

  • ✅ Removed Layout import (not needed)
  • ✅ Removed VerticalLayout() (caused error)
  • ✅ Simplified to only use tracers
  • ✅ Added safety check for empty cache
