Abstract: With the increasing of jewelry consumption, jewelry auction function as a new form of jewelry trading has attracted more and more attention. However, with the expanding of the jewelry auction market and the explosive growth of the information of jewelry auction, the traditional one-dimensional information presentation method has been difficult to meet the needs of the consumers. Information visualization, as a data mining technology, can integrate complex data information into intuitive visualization charts and present them in an interactive way, reduce data confusion and help users make better decisions. In view of the problems such as single presentation form, poor readability and unintuitive presentation from the traditional way of data collection, this paper uses data mining technology, Python and ECharts as the main visualization tools to propose the basic visualization mode of jewelry auction information. Finally, with the example of the jewelry auction results of Sotheby's in 2018, the visualization model is used to visually present different types of data. And based on the above research, the application value of visualization for jewelry auction information is summarized.
