• Develop interactive visualizations: color-coded reactable heatmaps, Highcharts boxplots with scatter overlays, master/detail trend charts, and donut charts
• Manage client-side interactivity:
  Shiny reactive event handling, JavaScript event bridges (Shiny.setInput
  
  Value()), and jQuery-based DOM interactions
