Skip to main contentSome data projects in VoxDash include multiple geographic maps that are hierarchically related, for example, a national map and corresponding state or provincial maps.
To help users explore this structure intuitively, VoxDash offers a drilldown map feature, allowing seamless navigation between high-level and detailed geographic views.
How It Works
When a data project includes nested maps (e.g., Country → State), VoxDash automatically displays the highest-level (most expansive) map first.
Even if a user has not uploaded a national-level map, VoxDash will promote the largest available map as the top-level view.
Users can then explore subregions by clicking directly on a region within the map. If detailed data is available, VoxDash will automatically drill down into the more granular map.
Example:
If a dataset includes both:
-
A United States map, and
-
State-level maps for California, Texas, and New York,
Then:
-
VoxDash will display the U.S. map as the entry point.
-
When a user clicks on California, they’ll be taken to a state-level map of California, where more detailed data may be shown.
-
If the user returns to the U.S. map, they can explore another region (e.g., Texas).
Alternate Navigation:
Users can also access detailed maps manually using the Drilldown Menu, which appears above the map as a dropdown or selection bar.
This allows users to:
- Switch between geographic levels (e.g., from Region to City),
- Compare data across areas,
- Or focus on a specific subregion without needing to click through the larger map.
