The <strong>Ruby Visualizer<\/strong> transforms Ruby classes, modules, mixin inclusions, and class hierarchies into clear, interactive class diagrams. By parsing attribute accessors (<code>attr_accessor<\/code>, <code>attr_reader<\/code>), module compositions (<code>include<\/code>, <code>extend<\/code>), and inheritance chains (<code>&lt;<\/code>), Ruby developers and backend architects can visually inspect object-oriented domain structures at a glance.<\/p>\n<h2>The Mechanics of Ruby Visualizations<\/h2>\n<p>In VPasCode, Ruby rendering automatically parses <code>class<\/code> declarations, <code>module<\/code> mixins, attribute definitions, and method signatures into structured UML-style class cards. Classes and modules serve as primary visual nodes, attribute readers list as fields, and inheritance or mixin inclusion keywords automatically generate relationship connectors between visual entities.<\/p>\n<h3>1. Essential Setup<\/h3>\n<p>To visualize a standard Ruby class hierarchy, define modules for shared behaviors alongside base classes and child implementations.
