Optimize map rendering performance by limiting point density and pre-aggregating offscreen data.
Use region maps to display statistical metrics per administrative boundary with topojson files.
Control tooltip content and field formatting to include contextual metadata with location markers.
Validate map coordinate alignment across different visualization types to prevent misrepresentation.

Module 6: Performance Optimization and Scaling Strategies

Size Elasticsearch heap and file system cache for workloads dominated by geo_shape operations.
Pre-filter queries using time ranges and routing keys to reduce spatial search scope.
