+- Anchors for users/customers
+- Multiple link types: dependencies, flows, labeled links
+- Evolution arrows and trend indicators
+- Custom evolution stages with optional dual labels
+- Custom stage widths using @boundary notation
+- Pipeline components with visibility inheritance
+- Annotations, notes, and visual elements
+- Source strategy markers: build, buy, outsource, market
+- Inertia indicators
+- Theme integration
+
+Implementation includes parser, D3.js renderer, unit tests, E2E tests, and comprehensive documentation.
