Visualization Research And Application Of The Relation Between Public Security Data

The continuous development of social economy has led to an increase in the regional mobility of the population,the amount of data accumulated within the public security organs is also increasing,and the correlation between data is also increasingly complex.The continuous development of information technology has prompted public security agencies to break the traditional methods of investigating cases.This paper visualizes the hidden relationships in the public security data through visual tools.Researching and analysising these seemingly scattered and disorganized data reveals hidden criminal clues and presents them in an intuitive and concise graphical form that can speed up the detection of cases.The visual research and application of the correlation between public security data remains a hot topic in the public security field,and many technologies and practices are not yet fully mature.Therefore,creating a data visualization system that is practical and has a good user experience is a very meaningful research.This paper focuses on the visualization of the relationship between public security data,and proposes a series of programs to realize the visualization of the association relationship between public security data,including: data import,visualization algorithm,data mapping,and visual display.Based on these schemes,the paper designs and implements a visualization system for the correlation between public security data.The system is divided into three modules: an integrated query module,a GIS analysis module,and a decision analysis module.The main research contents of this paper are as follows:(1)After comparing,researching and analyzing various data visualization tools,D3.js was finally selected as a data visualization tool,because D3.js has enough freedom to meet the secondary development requirements,the system is based on D3.js to extend the functionality.(2)This paper analyzes the main problems faced by the relationship between public security data,and designs and implements a system for solving these problems.This paper will study and analyze this system in detail,including: requirements analysis,system design,systemimplementation,and system testing.(3)This paper analyzes the technical architecture and structural design of the visualization of the association relationship,and introduces the successful practice in the public security data association relationship visualization system.(4)For different visual display requirements of users,point-value method,force layout algorithm,tree-like graph layout and other algorithms were studied,and a visualization system for correlation between public security data was developed and implemented.The research content of this paper comes from a practical project.It uses efficient layout algorithms for different needs to show the relationship between public security data.The system provides interactive visualization capabilities,including dragging and zooming on parts of the graph or overall graphics.Through the research and analysis of the relationship graphs presented in the system,it provides favorable support for the public security department to detect and solve cases and maintain social stability.The realization of this system has achieved good application results.
