The <strong>C++ Visualizer<\/strong> transforms C++ class definitions, structs, abstract base interfaces, and inheritance chains into clear, interactive class diagrams. By parsing class members, access specifiers (<code>public<\/code>, <code>protected<\/code>, <code>private<\/code>), virtual methods, and inheritance linkages, systems programmers and software architects can visually inspect object-oriented architecture and memory ownership models at a glance.<\/p>\n<h2>The Mechanics of C++ Visualizations<\/h2>\n<p>In VPasCode, C++ rendering automatically parses <code>class<\/code> and <code>struct<\/code> declarations, access sections, virtual function contracts, and inheritance specifications into structured UML-style diagrams. Classes serve as main entity cards, access specifiers dictate field and method visibility groups, and inheritance keywords (including multiple inheritance) generate distinct relationship connectors between class nodes.<\/p>\n<h3>1. Essential Setup<\/h3>\n<p>To visualize a standard C++ class hierarchy, define abstract base classes with pure virtual functions (<code>= 0<\/code>) alongside derived class implementations. Standard object hierarchies like geometric shapes or renderable objects demonstrate fundamental class relationships:<\/p>\n            <div class=\"vpascode-viewer-container vpascode-fancy-active\">\r\n                                <div class=\"vpascode-header\">\r\n                    <span class=\"vpascode-lang-label\">C++<\/span>\r\n                    <a href=\"https:\/\/www.vpascode.com\/#cpp: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\" \r\n                       target=\"_blank\" \r\n                       rel=\"noopener noreferrer\" \r\n                       class=\"vpascode-fancy-btn\">\r\n                        <svg width=\"14\" height=\"14\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\" style=\"margin-right: 8px;\"><path d=\"M11 4H4a2 2 0 0 0-2 2v14a2 2 0 0 0 2 2h14a2 2 0 0 0 2-2v-7\"><\/path><path d=\"M18.5 2.5a2.121 2.121 0 0 1 3 3L12 15l-4 1 1-4 9.5-9.5z\"><\/path><\/svg>\r\n                        <span>Edit C++ in VPasCode<\/span>\r\n                    <\/a>\r\n                <\/div>\r\n                                <div class=\"vpascode-code-wrapper\">\r\n                    <pre class=\"lang-cpp\"><code data-language=\"cpp\" class=\"language-cpp\">#pragma once\r\n#include &lt;iostream&gt;\r\n#include &lt;string&gt;\r\n\r\n\/\/ Abstract base interface\r\nclass Renderable {\r\npublic:\r\n    virtual ~Renderable() = default;\r\n    virtual void render() const = 0;\r\n};\r\n\r\n\/\/ Base class for geometric shapes\r\nclass Shape : public Renderable {\r\nprotected:\r\n    std::string name;\r\n\r\npublic:\r\n    Shape(const std::string&amp;
