Designing Visualizations with Tableau

In the world of data analysis, Tableau stands out as a powerful tool for visualizing complex information in an easily understandable format. Let's take a closer look at how a Tree Map visualization was created to reveal the quantity of items ordered in a specific data set.

The journey begins with opening the Product data file, which contains detailed information about the various products. To add more depth to the analysis, an inner join was established between the Product and OrderDetails data files, using the common key ProductID. This connection allows for a comprehensive view of the products and their corresponding orders.

The PropertyInfo file was also added to the mix, and an inner join was created between OrderDetails and PropertyInfo files, using the common key PropertyID. This additional data provides valuable context about the properties where the orders were placed.

With all the necessary files in place, the Quantity and Product Category fields were selected to focus on the quantity of items ordered and the categories they belong to. The "Text Table" option was chosen to present the data in a clear, easy-to-read format.

To drill down into the data, the Quantity field was clicked, and users discovered that Furnishings have the highest quantity of items ordered, followed closely by Maintenance, Public Areas and Housekeeping, and Office Supplies. Maintenance, it seems, is slightly larger in terms of quantity of items ordered compared to Office Supplies.

The Tree Map visualization, a key feature of Tableau, uses color and size to indicate the largest quantity values. This makes it easy for users to spot trends and patterns at a glance.

It's worth noting that Tableau is not limited to this specific data source. Users can connect datasets from various sources, making it a versatile tool for data analysis. Furthermore, Tableau comes equipped with an in-built "Superstore" dataset, providing a ready-to-use data source for testing and learning purposes.

In conclusion, the Tree Map visualization in Tableau offers a compelling way to explore and understand the quantity of items ordered across different product categories. By selecting the Quantity and Product Category fields and using the "Text Table" option, users can gain valuable insights into their data, helping them make informed decisions.
