# Heat Map

**Density maps**, also called <mark style="color:green;">heatmaps</mark>, can be used when you want to show a trend for visual clusters of data.  Signifies areas of low and high density.

You can use Heatmap to:

* Visualize the density of an object (i.e. how many stores, events...) in certain areas
* Visualize the magnitude of value of an object (i.e. how high is the temperature, revenue, population...) in certain areas

For example, if you want to find out which areas of Manhattan have the most taxi pickups, you can create a density map to see which areas are most popular.

## Building Your Heat Map

### <mark style="color:red;">**\***</mark>**&#x20;Location**

* Specify the geographic location of your data points (e.g., city, country, continent).&#x20;
* Once a field is dropped, select its appropriate geographic role from the dropdown menu.

OR

### <mark style="color:red;">**\***</mark>**&#x20;Latitude & Longitude**:&#x20;

Provide the exact coordinates for each location.&#x20;

Drag latitude (y) and longitude (x) fields to define map coordinates.&#x20;

### **Size** (Optional)&#x20;

Use this field to vary the size of the density marker for data points according to values.&#x20;

## Formatting Your Point Map

#### **Title**&#x20;

This allows you to give a Title to the Line Chart. You just need to go to the Title section in the Format panel.

You can easily toggle it on or off.  In the "Customize title" modal, you can:

**Colors**

Color scale: Here you can choose from predefined color palettes or create a custom gradient scale for your density marker.

Color customization:&#x20;

* The colors are applied to the density marker, You can customize the colour scale using the edit colour scale modal.
