Data Visualization in Environmental Public Health: From Data to Insight
Figure 4 Point Map Example: Inspection Locations
Point Maps Point maps display the locations of
individual features or events. Point maps work well when the exact location of each event or observation is important. Keep the number of points manageable and keep individual locations visible. If too many points overlap, consider using a graduated symbol or density map instead. Examples include: • Food establishment locations • Mosquito trap sites • Water sampling locations • Complaint locations
