• Familiarity with Java2D / Graphics2D, SVG, or vector graphics rendering.

• Evaluate existing charts and determine the best migration path (standard, customizer, or custom code).
• Implement complex chart features including custom annotations, markers, axis formatting, and legend placement.
• Lead POCs for high-complexity charts to identify technical risks and estimate development effort.
• Recommend technical workarounds where 1:1 parity is not available out-of-the-box.
