Some 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:
  1. VoxDash will display the U.S. map as the entry point.
  2. When a user clicks on California, they’ll be taken to a state-level map of California, where more detailed data may be shown.
  3. 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 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.
