Research On Thematic Application Analysis Based On Data Visualization

Thematic analysis is an analysis of a specific problem or a specific topic.Thematic visualization analysis is an important part of thematic analysis,which makes thematic analysis more visualization,comprehensive and three dimensional.Therefore,thematic visualization analysis has important research significance and application value.Based on the data visualization theory,this paper explores the methods and technologies involved in thematic application,and analyzes the thematic visualization of the Olympic Games.The main contents in this paper are as follows:1.The basic concepts,design principles,chart usage rules and analysis process of data visualization were summed up in this paper.The problems and details that should be paid attention to in the stage of visualization mapping and visualization presentation were analyzed in detail by combining the visualization graphics with the practical working scenes to provide "personalized" design ideas from the perspective of design science.2.Through the comparison of the advantages and characteristics of various data visualization tools,analysis and research for cases application of thematic visualization on the big data in the Olympic Games are implemented based on Python and visualization tools ECharts?Antv?Power BI.Combined with the theme of big data in the Olympic Games,this paper shows the implementation on analysis and research for cases of thematic application based on data visualization and explores the value-orientated tendency of Winter Olympics in China by comparing the Gold medal values in different Olympic sports.Take this for instance,this paper explores how to reasonably use statistical methods and visualization tools in thematic visual presentation,so as to achieve more three-dimensional and deeper presentation of target topics.
