The heat map is used to visualize the data in the form of size and color on different measures.
Two different measures are visualized simultaneously using a heat map. One measure is assigned to size, whereas another measure is attached to the color of the heat map.
For example, consider the data source such as the Sample-Superstore and its dimensions and measures.
The procedure to create a heat map is given step by step as follows:
Step 1: First, go to the worksheet.
Step 2: Hold the Ctrl key in the keyboard.

Step 3: Select the dimension Sub-Category and measure Sales as shown in the following screenshot.

Step 4: Click on the “show me” button of the worksheet.
Step 5: And select the Heatmap icon, as shown in the following screenshot.

Step 6: Drag measure Profit and drop into the Color shelf under the Marks pane.

Step 7: Drag the dimension Region and drop into the column shelf.

After completing all the above steps, it creates the Heatmap, which is used to visualize the Sales field and Profit field across different the dimension.

Tableau Tree Maps

The treemap displays the data in nested rectangles. The dimensions define the structure of the treemap and measures determine the color or size of the individual square.
The squares are easy to visualize as the size and shade of the color of the square reflects the value of the measure.
A Treemap is created using one or more dimension with one or two measures.
For example, consider the data source such as Sample-Superstore, if you want to find the size of Profits for each ShipMode values. Below are the following steps to create a treemap.
Step 1: Drag the measures Profit and drop into the color shelf under Marks pane.
Step 2: Again, drag the measures Profit and drop into the Size shelf.

Step 3: Drag the dimension Ship Mode and drop into the Label shelf.

Step 4: Choose the treemap option from the “show me“.

After completing all the above steps, it creates the treemap shown in the below screenshot.
