| Data journalism is a new reporting mode derived from the wave of big data.Supported by computer technology,it USES data to tell stories in content and visualization to present in form.Through data collection,mining and analysis,it mines the deep meaning behind data.As the terminal link of data news presentation,visualization results directly affect the audience's understanding and cognition of data news information.In recent years,data news visualization has attracted more and more attention from domestic media.However,from the general application status,both the academic theoretical research and practical exploration in the industry are relatively weak.It is the research significance of this paper to explore the current situation of visualization production practice of domestic data news media,find out the commonness and deficiency,and then put forward the corresponding optimization strategy.Throughout the domestic data news media,the "data news" column of xinhuanet,as the industry leader,explores the current situation of its visualization production practice,which can not only reflect the trend and characteristics of the development of domestic data news visualization,but also highlight the commonness and deficiency in the current situation of other domestic data news media visualization.Under the opportunity,in this paper,the xinhua news "," data columns as the research object,adopts content analysis method,from the card the information visualization process model put forward,focusing on the analysis of the xinhua news "data " column in the data source,visual design,view shows the four stages and interaction design practice of the status quo,summarizes the experiences of the columns in the visual practice and characteristics,to explore the spread of the data visualization news development path.The introduction mainly expounds the academic value and practical significance of the research in this paper.By combing the research results of data news visualization at home and abroad,it demonstrates the necessity and feasibility of this paper's research on the practice of data news visualization in xinhuanet,and elaborates on the theoretical basis,research ideas and research design.Chapter one is an overview of data journalism visualization.Firstly,the related concepts of visualization and data news visualization are analyzed.Secondly,thedevelopment context and common forms of data journalism are summarized.Finally,starting from the process model of information visualization proposed by card et al.,this paper summarizes the production mode of data news visualization,namely: data source,visual design,view display and interaction design.The second chapter quantifies the research samples from the production flow model of data news visualization.The characteristics of xinhuanet in each link are analyzed and summarized based on the statistical results of various samples.In the third chapter,according to the sample analysis of the visualization report of xinhuanet,the data of xinhuanet can be summarizedThree characteristics of visualization: authority of data sources and channels,exploration and innovation of visual design,and diversified development of interactive forms;On this basis,three major advantages of data news visualization of xinhuanet are summarized:Mining data relation and revealing deep meaning;Through data integration,tell the story behind.The fourth chapter,on the basis of content analysis,summarizes and analyzes the problems existing in the practice of data news visualization of xinhuanet,and puts forward the corresponding optimization development strategy. |
