## Data Configuration

#### Chart Type

You can read about this section [here](/creating-dashboards/visualizations/data-tab#chart-type).

#### Geospatial Data

* **Latitude Column**: Choose the column that stores latitude data. It must be of float type.
* **Longitude Column**: Choose the column that stores longitude data. It must be of float type.
* **Row Limit**: Restrict the number of rows of data displayed as markers on the map. The map is more performant when there are fewer data points drawn.
  The maximum row limit is 5000.

#### Filter

Read about the `Filter` section [here](/creating-dashboards/visualizations/data-tab#filter).

## Formatting

#### Header

Read about the `Header` section [here](/creating-dashboards/visualizations/format-tab/overview#header).

#### Map Options

* **Map Style**: Define the visual style of the map.
* **Save Initial View**: Configure the position, orientation, and zoom of the map that is shown when the map first loads.

#### Density

* **Intensity**: A multiplier primarily used to adjust the appearance of the heatmap.
* **Opacity**: Sets the transparency level of the density map layer.
* **Color Zones**: Defines the heatmap's color gradient. Multiple threshold values can be set between 0 and 1.

#### Enable Download

Read about the `Enable Download` section [here](/creating-dashboards/visualizations/format-tab/overview#enable-download).

#### CSV Download

* **Tab Delimited:** This specifies if the CSV download exported from the data table should have values separated
  by tabs. If not turned on, the separators will be commas.

#### URL Link

Read about the `URL Link` section [here](/creating-dashboards/visualizations/format-tab/overview#url-link).

#### No Data Configuration

Read about the `No Data Configuration` section [here](/creating-dashboards/visualizations/format-tab/overview#no-data-configuration).

#### Expose Underlying Data
