J SVG Fundamentals
This example demonstrates fundamental SVG rendering techniques, showcasing a structured diagram with geometric shapes—rectangles, paths, and lines—arranged in a schematic layout. Colored blocks in blue, gray, orange, and green sit within outlined panels, connected by dashed black guide lines with subtle drop shadows. The visualization uses raw SVG elements like `<rect>`, `<path>`, and `<filter>` definitions directly in HTML, with no external JavaScript libraries. It relies on SVG filters for shadow effects and fixed viewBox coordinates to lay out the composition, illustrating how static vector graphics can be constructed purely through declarative markup.
