To visualize our data on the map we need to convert longitude and latitude to dimensions. In **Measures** select **Latitude** (1) and open the field's dropdown and select **Convert to Dimension** (2). Do the same for the **Longitude** measure.

Drag the **Longitude** measure to the **Columns** and the **Latitude** measure to **Rows**. Automatically the map of **Belgium** will appear with little dots representing the cities in out data set.

You will now have a map, with dots of various sizes. The size indicates the number of call center interactions for that specific city. To vary the size of the dots, navigate to the right panel and open **Measure Values** (using the drop down icon). From the drop down list select **Edit Sizes**. Play around with different sizes.
