# Heatmap Chart Overview

The Heatmap chart can be used to explore the relationship between variables in your dataset. The heatmap displays values from the specified column atop a colored correlation matrix. The chart is also interactive, allowing users to hover over a cell to spotlight the cell along with its column and row.

An example of the Heatmap Chart.

## Steps to Create a Heatmap Chart:

1. Click the **Show Charts** button on the top-right of the window.
2. Click **Add Chart** > **Heatmap Chart**.

A settings panel will appear, allowing you to configure the heatmap chart.
