By concentrating on the top five diseases, the system enabled stakeholders to identify trends, demographic impacts, and geographic hotspots. The research utilized descriptive and applied methodologies to determine key performance indicators, design user-friendly interfaces, and evaluate the system's usability through the System Usability Scale (SUS), which yielded an "Excellent" rating. Through Extreme Programming, the system addressed critical gaps in health data interpretation by providing accessible, actionable insights for public health officials, healthcare providers, and the community. The visualization system fostered better decision-making, enhanced health awareness, and supported targeted interventions.ix, 67 p. : ill.
