The document explains how to create and utilize tree maps in Tableau, which display data in nested rectangles defined by dimensions and measures. Tree maps provide a visual representation of data that allows for quick comparisons across different categories, though they can be misused if not applied correctly. Instructions are provided for creating a tree map using sample data, with steps for incorporating multiple dimensions and measures.

- 2. The tree map displays data in nested rectangles. The dimensions define the structure of the tree map and measures define the size or color of the individual rectangle. The rectangles are easy to visualize as both the size and shade of the color of the rectangle reflect the value of the measure. A Tree Map is created using one or more dimension with one or two measures. Tableau - Tree Map
- 3. Use tree maps to display data in nested rectangles. You use dimensions to define the structure of the treemap, and measures to define the size or color of the individual rectangles. Treemaps are a relatively simple data visualization that can provide insight in a visually attractive format. A tree map is a visualization that nests rectangles in hierarchies so you can compare different dimension combinations across one or two measures (one for size; one for color) and quickly interpret their respective contributions to the whole. When used poorly, tree maps are not much more than an alternative pie chart. Uses of Tree map
- 4. Using the Sample-superstore, plan to find the size of profits for each Ship mode values. To achieve this objective, following are the steps. Step 1 − Drag and drop the measure profit two times to the Marks Card. Once to the Size shelf and again to the Color shelf. Step 2 − Drag and drop the dimension ship mode to the Label shelf. Choose the chart type Tree Map from Show Me. The following chart appears. Creating a Tree Map
- 6. Tree Map with Two Dimensions You can add the dimension Region to the above Tree map chart. Drag and drop it twice. Once to the Color shelf and again to the Label shelf. The chart that appears will show four outer boxes for four regions and then the boxes for ship modes nested inside them. All the different regions will now have different colors.
