2. Interactive Maps – Visualizes crime incidents geographically, highlighting hotspots and patterns using heatmaps.

3. Trend Analysis – Shows historical trends of crime types (e.g., theft, assault, cybercrime) over time.

4. Filtering Options – Users can filter data by location, crime type, time period, or severity.

5. Statistical Dashboards – Displays charts, graphs, and summaries of crime frequency, rate, and distribution.

6. Predictive Insights (Optional) – Uses data analytics or machine learning to forecast potential crime trends in specific areas.

7. Public Alerts & Notifications – Notifies citizens about high-risk areas or recent criminal activity.

8. Export & Reporting – Allows users to download crime reports in PDF, Excel, or CSV formats.

9. User-Friendly Interface – Simple navigation and responsive design for desktop and mobile access.
