Tableau for Data Analyst – Tableau Tree Maps

Personal Career & Learning Guide for Data Analyst, Data Engineer and Data Scientist

A tree map is a type of graph that is commonly used by data analysts to display hierarchical data. It is a rectangular area that is divided into smaller rectangles, with each rectangle representing a different level in the hierarchy. The size of each rectangle is proportional to the value it represents, making it easy to see the relative importance of each level in the hierarchy.

Tableau is a data visualization software that makes it easy to create tree maps and gain insights from your hierarchical data. With Tableau, data analysts can quickly and easily create a tree map, customize the appearance of the graph, and interact with the data to explore relationships and identify patterns.

To create a tree map in Tableau, you first need to connect to your data source. This could be a database, spreadsheet, or any other type of data file. Once you have connected to your data source, you can drag and drop the fields that you want to display in the tree map onto the Rows and Columns shelves.

Next, you need to choose the type of tree map that you want to create. Tableau offers several different types of tree maps, including standard tree maps, nested tree maps, and treemap with color. Each type of tree map has its own unique features and uses, so it’s important to choose the right type for your data.

Once you have created your tree map, you can customize the appearance of the graph by changing the color, size, and other formatting options. You can also add reference lines, labels, and annotations to provide additional context and insights.

One of the key benefits of using Tableau to create tree maps is the ability to interact with the data. You can hover over the rectangles on the tree map to see the underlying data, or use filters to highlight specific levels or ranges in the hierarchy. This makes it easy to understand the relationships between the levels in the hierarchy and identify patterns and trends.

In conclusion, tree maps are a powerful tool for data analysts to visualize and understand hierarchical data. Tableau makes it easy to create and customize tree maps, and provides interactive features that allow you to explore and understand your data in more depth. Whether you are a seasoned data analyst or just starting out, Tableau is a great tool for creating tree maps and gaining insights from your hierarchical data.
