The scientific research ability is one of the important factors which affect the strength of colleges and universities. Through data analysis and visualization, the scientific research level of universities and teachers can be displayed intuitively. In order to better reflect the scientific research level of colleges and universities, this paper designs and implements the scientific research data visual- ization system. This system uses the PyCharm development platform, uses Bootstrap for page layout to form the overall structure, us- es SqlAlchemy to operate the database in the background, and transmits data through the Flask Web framework. According to the characteristics of data visualization, different types of data charts are drawn by ECharts technology, and the synchronous display of data is completed withAjax asynchronous request.
