source ~/.zprofileOption B (Oracle Installer):
Download from Oracle Java Downloads
🔹 Step 3: Verify
java -version✅ PART 2: Install PlantUML
🔹 Step 1: Install Graphviz
brew install graphviz🔹 Step 2: Install PlantUML
Option A: Download plantuml.jar from plantuml.com/download
Option B: Homebrew install:
brew install plantuml✅ PART 3: Run PlantUML
🔹 Option A: Using JAR
