A map chart positions your data in a context, often geographical, using different layers. The layers can be either data layers, such as marker layers or feature layers, or reference layers, such as map layers, Tile Map Service layers (TMS), Web Map Service layers (WMS), or image layers. By adding different layers to the map chart, you can configure the map to suit your needs.

The data you use to create a map chart often has geographical context, such as columns with latitude and longitude values, or names of countries and cities.

You can add more than one layer of each layer type and control the properties for each layer separately. Zoom and pan using the navigation controls in the visualization to explore the data in the map chart.

• Each layer contains its own set of properties to add fine control for the specific type of layer.
• Transparency, a property in each layer, gives you fine control over the layer display.
• The marker layers can add indicators for a data column, such as locale or zip codes, major cities, or country names.
• The feature layers can add shapes defining areas such as regions, countries, or continents.
• The image layers can be used as both geographical and non-geographical backgrounds in your maps.
• Third-party services (TMS and WMS) can be used to add specific field interest or beauty to the map charts.
