  • Selectable offence types, reporting years (2013–2024), and reporting criteria
  • Time-series bar chart tracking the selected offence and district across all reporting years
  • District-level detail on hover, with instant recalculation of statistics and map colouring

Technical

Data pipeline consolidates multiple years of BKA and state-level PKS releases (Excel/CSV) into a unified spatial dataset, joined to district shapefiles for mapping. Built and deployed as a standalone R Shiny application.
