This interactive map identifies potential quarantine zones by combining two spatial criteria: proximity to the ZIP code with the most patients and areas with high child populations. Users adjust buffer distance and population thresholds, triggering a workflow that queries ArcGIS FeatureLayers, buffers geometries with `geometryEngine.buffer`, unions filtered ZIP code polygons, and intersects results using `geometryEngine.intersect`. The map renders patient data via a ClassBreaksRenderer and displays the final intersection polygon as a semi-transparent overlay.
