Geo Charts (Pushpins)
Geo charts (pushpins) show data broken down geographically. Geo charts show data points as bubbles using the coordinates from the location attribute. In addition, geo charts can display the size of the bubbles in proportions using another metric. If you add an attribute to the Segment by section, the bubbles get different colors for each value.
Geo charts (pushpins) have the following sections:
- Location
- Metric (Size)
- Metric (Color)
- Segment by
- Configuration
For information about common characteristics and settings of all visualizations, see Visualization Types.
To set a specific part of the map to be seen when you open the visualization, go to Configuration → Map → Default viewport and select a part of the map.
For the configuration options common for all visualizations, see Configure Visualization Properties.
Access tokens
GoodData.CN users must acquire and upload a special access token from Mapbox to enable geo charts. GoodData Cloud users are provided with this access token automatically, however, they can use their own access tokens as well.
For details, see Upload Access Tokens for Geo Charts

For information about the preparation of data for geo charts (pushpins), see Configure Data for Geo Charts.
Examples
Location Display
This example displays how the shops are distributed.
Put the Position attribute in the Location section. Each dot represents the location where a shop is present. All dots have the same size.
For large maps, you can group nearby points so that the displayed map is not overcrowded. In the Configuration section, go to Points and select Group nearby points.
The following images show identical data - ungrouped and grouped.
Dot Size Based on Value
If you want to see a different size of the dots based on the metric value, add a metric to the Metric (size) section.
To adjust the size of the smallest and largest dots, go to Configuration → Map → Points and select the value in the dropdown menus.
Dot Color Shade Based on Metric Value
If you put an item to the Metric (color) section, the data displays different shades of the color based on the metric value.
Dot Color Based on Attribute Value
If you put an attribute to the Segment by section, the data displays different color for each attribute value.
