This interactive visualization presents homicide cases across different U.S. states, using a simple HTML, CSS, and JavaScript setup within a React framework. The page currently displays a static "Hello HTML!" message, showing the foundational structure rather than a live chart. It relies on basic DOM manipulation and inline styling, with no advanced libraries like d3.forceSimulation or Canvas rendering yet implemented. The example serves as a minimal starter template, leaving the actual state-by-state homicide data mapping for future development.
