REPEATED PATTERN

Repeated SVG Pattern Map

Repeated Pattern Type	SVG Code Pattern	Occurs Multiple Times For
Stage Box Pattern	<rect x="[X]" y="[Y]" width="[W]" height="[H]" rx="[corner]" fill="[color]" /> <text x="[CENTER-X]" y="[CENTER-Y]" font-size="[size]" text-anchor="middle"> [Stage Name] </text>	Used for every process stage such as: Preliminary Data Preliminary Model Testing Evaluation Refinement Mature System
Connection Arrow Pattern	<line x1="[start-x]" y1="[start-y]" x2="[end-x]" y2="[end-y]" stroke="[color]" stroke-width="[size]" marker-end="url(#arrow)" />	Used for every directional flow between stages in the process diagram.
Stage Label Pattern	<text x="[center-x]" y="[center-y]" text-anchor="middle"> [Stage Name] </text>	Repeated for labeling each stage box inside the diagram.
