Abstract: The amount of users who pay close attention to some project on a certain scale is one of the important evaluation parameters to analyze the development of the industries in which these projects are located. It is the basic data to research the trend of industry development. But it is difficult to obtain the information of the projects in most cases and it has motivated a research to relax this requirement with a data acquisition and analysis system which has been designed and implemented. The system performs multi-dimensional analysis on changes of the objects including the quantity and the attention based on the number of stars, forks and issues related to the key projects obtained from GitHub. To be more intuitive, data visualization realized by Baidu Echarts provides a reference for studying the overall trend of industry development.

Key words: GitHub, data acquisition, Python, REST API, Echarts
