With the popularization of higher education, the number of college students is increasing year by year. The analysis of freshmen's data can help the school to better understand the situation of students, and help to carry out teaching, student management and other work. Based on this, this paper designs and implements the freshmen data visualization system, summarizes the freshmen data, and displays the data through the college screen. The system is based on Python language and is realized by separating the front end and the back end. The back end provides the data interface through Python flash framework and SqlAlchemy, the front end and back end transfer data throughAjax, and the front end uses Vue + ECharts to visualize the data.
