Abstract: To show and analyze the feature of attribute flow in majors distributary data,a sunburst matrix visualization method was proposed in the paper.The data with various attributes are firstly selected and counted in the method.The statistical data are mapped to the visual elements of visualization results.The mapping procedure includes three parts.In the first part,the scattered bubble charts are introduced to express the whole statistical numbers of student with various source and destination.Secondly,contrast method of pie chart is introduced into bubbles to show its gender proportion.The pie chart is adopted as the inner layer of sunburst.Thirdly,the students’ grade point attribute in each category are designed to display comparably in the outer layer of sunburst.The experimental results and the evaluation of the mana-gement staff denoted that the visualization results can be expressed directly to the flow characteristics such as the number of students,gender proportion,and grade point and so on.The detailed classification of students and professional construction and training are expected to achieve according to the visualization results.
