In recent years, in the face of massive data, people hope to have new technologies and tools to analyze large amounts of data, and data mining technology has become the best way to achieve decision-making and support. Data mining is a process of mining previously unknown, valid and usable information from a large database, and using this information to make decisions or enrich knowledge.
The emergence of Diagram provides a graphical representation of data. Visualizing data through charts can intuitively show and mine the relationship, distribution, category trends and patterns of data. Different types of diagrams can be created to show the relationship between data, find the correlation between data, and dig out valuable information.
The SuperMap desktop supports the creation of different forms of Diagrams to visualize Dataset Properties information. Through the construction of charts, we can intuitively display and mine the relationship, structure and trend of data. It is often used for classified statistics or comparison. For example, a bar chart can be used to visually display the total GDP of different provinces in the country and compare the GDP differences of different provinces. It can also be used to count the frequency distribution of events, such as the distribution of product quality of a factory, and to judge and predict product quality and unqualified rate.
From the SuperMap Desktop, you can:
- Rich Chart types are provided, including column chart, pie chart, line chart, bubble chart, combination chart, scatter chart, time sequence chart, histogram, bar chart, doughnut chart, area chart, etc.
- Support the mutual conversion between Diagram and thematic map, and quickly display Data Information in different ways.
- Support the linkage display among charts, maps and attribute tables, and various visual interactive operations, so that the display effect of different charts can be seen at the same time.
- Support DiagramExport as Image, which can be applied to other document tools such as Word and PPT
- The Diagram Template is provided, and the user can directly make the Diagram according to the template provided by the program. At the same time, export the chart style as a template for repeated use.
- Support inserting the completed Diagram into the layout and map screen for use.
Examples
The following map shows the traffic congestion in various districts of Beijing during the morning rush hour. From the thermal map, we can see the distribution of hot spots and cold spots of congestion, and understand the general location distribution of congestion as a whole, but we can not understand more accurate congestion information from the map.

In order to mine more in-depth Data Information, we can use Diagram to analyze road congestion to obtain more in-depth information, and provide auxiliary decision-making for traffic management departments to guide traffic flow, timely release of traffic information and response measures, so as to improve the efficiency of road traffic.
