Map chart
A map chart uses a map to show how data is distributed across a geographic region.
Prophecy provides two types of map charts: a marker map and a displacement map.

The option to select a map chart only appears when the dataset contains geo points in WKT format.

A marker map chart uses pins to visually represent each data point on a map.
You can configure the following parameters for the chart:

| Tooltip Columns | Column that contains information that will show up in the geo point tooltip. |
| Fit Bounds | Whether to fit the map to the bounds in the points. |

| Parameter | Description |
