When to use this template
This visualization helps analysts quickly identify the spatial distribution and co-location of distinct categories of points of interest. It is ideal for scenarios where recognizing specific types of locations is critical for navigation, resource allocation, or understanding service availability within a geographic area, rather than simply showing raw counts.
- Geospatial point data with latitude and longitude.
- Categorical attribute for each point (e.g., type, function).

- When distinguishing specific categories is more critical than exact counts.
- Discrete points of interest, not continuous spatial phenomena.
- Data requiring efficient rendering of many distinct symbols.
