An interactive map paints geographic maps sourced from a 3rd party provider, with several optional overlay layers for data display. It is an excellent choice for displaying large amounts of geo-based information in relevant detail.
The following steps demonstrate how to create an interactive map visual on the dataset
National Geographic Features. The data for this dataset came from the United States Board on Geographic Names; we recommend choosing the download of the
AllStates zip file because it is easier to process. Additionally, you may wish to use
Feature Class Definitions and State Abbreviations to supplement the dataset.

In the visuals menu, find and click interactive map, the second choice on the fourth row.
Note that the shelves of the visual changed. They are now Geo, Measures, Dimensions, Tooltips, and Filters.
The only mandatory shelf for interactive map visuals is Geo.
Populate the shelves from the available fields (Dimensions, Measures, and so on) listed in the left navigation menu.
Prim Lat Decand drag it over the Geo shelf on the main part of the screen. Drop to add it to the shelf.
Prim Long Dec, and drag it over the Geo shelf on the main part of the screen. Drop to add it to the shelf.
On the Geo shelf, cast the field
Prim Lat Dec to
Latitude, by selecting Change Type Geo Latitude.
Similarly, cast the field
Prim Long Dec to
Longitude, by selecting Change Type Geo Longitude.
Notice that the two converted measurements have a (globe) icon tag. This indicates that these feels can be 'understood' as geographic fields.
Under Dimensions, select
Feature Id, and drag it over the
Measures shelf. Drop it on the shelf.
If you leave the Measures shelf empty, the system uses the value
1, and does not require an aggregate.
count(Feature Id), by selecting Aggregates Count.
Click Refresh Visual to see the basic interactive map.
The one we have here is a Google INEGI map.
Notice that in this representation, there is significant overlap from on the Heatmap Layer. However, you can see the boundaries of each region by hovering the pointer over a section of the map. The total count of measurements in each region is in the circle inside the region. This comes from the Cluster Layer. Both the Heatmap and Cluster layers are on my default.
To see more detail, manipulate the map through magnification changes. You can also click on the map and manually 'pan' it to the area of interest. The following image shows that the regions automatically adjust into smaller sections, and you can see both greater detail and more individual 'totals'.
The 'interactive' part of this visual is that after clicking on a region to zoom-in and reposition, to the level of an individual marker, you can enable click behavior.

Above the left navigation bar, click Save.
There are many interesting visualization options. To change the tile layer, or the base map from Google to Mapbox, see Interactive Maps; Tile Layers. To configure the layer options, see Interactive Maps; Layer Options.
