# Heatmap Charts

> Create heatmap visualizations in Omni to display data density and patterns using color gradients across two-dimensional grids.

## Examples

**Heatmap:**

## Data Structures

Heatmaps can work with pivoted or unpivoted data, using 2 dimensions and one measure, or with all dimensions where there is a numeric available for the color facet. They often use two time facets, for example:

* `date` & `hour_of_day`
* `week` & `day_of_week`
* `month` & `year`

## Configuration

There is no heatmap specific configuration, but [color](/visualize-present/visualizations/configuration/color) and [tooltip](/visualize-present/visualizations/configuration/tooltips) controls may be relevant.
