Treemap

1) Treemap is a sophisticated visualization tool that effectively represents hierarchical data by displaying it as a series of nested rectangles. Each rectangle's size is proportional to a specific data value, making treemaps ideal for quickly grasping the relative magnitude of multiple categories. 

2) This type of chart is especially important for identifying patterns or anomalies in large datasets, helping improve data-driven decision-making in business analytics. Treemaps optimize space and visually simplify complex information, which is crucial for presentations and reports.

3) Application Scenario：Rectangular tree charts effectively illustrate data proportions within hierarchical structures and allow for hierarchical drilling to display lower-level data. For instance, these charts can visualize contract amounts where each color represents a year, and individual squares within that color indicate product categories. Rectangular tree charts facilitate a clear view of both annual and product-specific contract values through the size of the rectangles, providing an intuitive visual representation of the data.

4) Basic Requirement：Basic requirements for rectangular tree charts are as follows.

5) Chart Feature

Advantage: Rectangular tree charts can display data with hierarchical relationships and comparisons between the same levels.

Disadvantage: Rectangular tree charts are not suitable for data with unclear hierarchical relationships or a large number of categories.

Data Preparation

1. Log in to the system as the admin, click My Analysis, select a folder, and click New Subject, as shown in the following figure.

2. Click Local Excel and click Upload Data, as shown in the following figure.

You can download the example data.Regional Data Analysis.xlsx

3. After the data is uploaded, click OK.

Component Creation

1. Click Component in the lower left corner.

2. Drag the Time of Contract and Client Name fields into the Dimension bar, and the Contract Amount field into the Indicator bar.

3. Click the Rectangular Tree Chart icon in Chart Type. The dimension fields are added to the Fine-grained bar in order and the indicator fields are added to the Size bar.

4. Drag the Time of Contract field to the Color bar, click the icon xxx and select Year from the drop-down list, as shown in the following figure.

Note:

The arrangement logic of the rectangular tree chart is from top left to bottom right, representing the values from large to small in order. If there is no comparison of size, the rectangular blocks with a length-to-width ratio close to 1 are selected as the arrangement order. You are not allowed to change the sorting method by default.

Graphic Property Setting

Click the icon and set the Scheme to Bright, as shown in the following figure.

You can set the parameters of Size, Label, Prompt, and Fine-grained. For details, see Graphic Properties.

You can also set the parameters of Legend, Grid Line, Background, Adaptation Display, and so on for the component. For details, see Chart Component Style.

Effect Display

You can view the effect on both mobile terminals and the PC.

The effect preview is as follows.

In conclusion, treemaps, or rectangular tree charts, are invaluable for visualizing hierarchical data, providing a clear, visual distinction of data proportions through nested rectangles. These charts are particularly effective for displaying complex data in an accessible way, enabling quick insights into relative sizes and relationships within datasets. Ideal for presenting financial data, such as contract amounts by product type and year, treemaps help stakeholders quickly grasp key information for strategic decision-making.
