In recent years, facing the continuous generation of massive data, there has been a demand for new technologies and tools to powerfully analyze large datasets. Data mining technology has emerged as the optimal approach for decision-making and support. Data mining refers to the process of discovering previously unknown, valid, and actionable information from large databases, then utilizing this information for decision-making or knowledge enrichment.
The emergence of diagrams provides a graphical representation for data. Through data visualization via charts, relationships, distributions, categorical trends, and patterns in data can be intuitively displayed and explored. By creating different types of diagrams, users can reveal interrelationships between data, identify correlations, and deeply extract valuable insights.
SuperMap Desktop supports creating various forms of diagrams to visualize dataset properties information. The construction of charts enables intuitive display and exploration of data relationships, structures, and trends. These are commonly used for categorical statistics or comparisons. For instance, bar charts can visually display total GDP across different provinces in China, highlighting regional GDP disparities. They can also be applied to analyze frequency distributions of events, such as quality distribution in factory products, helping determine and predict product quality and defect rates.
In SuperMap Desktop, you can perform the following operations:
- Offers a variety of chart types including bar charts, pie charts, line charts, bubble charts, combination charts, scatter plots, time series charts, histograms, column charts, doughnut charts, area charts, etc.
- Supports mutual conversion between diagrams and thematic maps, enabling rapid data information presentation through different methods.
- Enables linked display between charts, maps, and attribute tables. Multiple interactive visualization operations allow simultaneous viewing of different chart presentations.
- Allows exporting diagrams as images for use in Word, PPT, and other document tools.
- Provides diagram templates, enabling users to create diagrams directly using predefined templates. Chart styles can be exported as templates for repeated use.
- Supports inserting completed diagrams into layouts and large-screen map displays.
Example
The following map displays morning rush hour traffic congestion in Beijing's districts. The heatmap shows distribution patterns of congestion hotspots and coldspots, providing general spatial understanding. However, precise congestion details cannot be discerned from the map alone.

To extract deeper data information, diagrams can be employed to analyze road congestion patterns. This provides auxiliary decision-making support for traffic management departments in guiding traffic flow, issuing timely traffic alerts, and implementing countermeasures, ultimately improving road network efficiency.
