  • Explore and apply emerging web visualization capabilities, including WebGL and browser-based real-time visualization, to support advanced 2D, 3D, and multidimensional spatial experiences
  • Evolve coding and development skills by staying current with JavaScript, TypeScript, complementary programming languages, development practices, coding tools, and user interface design techniques

Requirements
