Research metrics, closely related to statistics and network analysis, benefit greatly from visualizations. This chapter introduces briefly some guidelines for visualizations (design or color selections) before describing the visualizations frequently used. We first introduce the Chart Chooser, which starts from the type of analysis required and then considers the characteristics of the data. This includes either static or interactive graphs that are common in statistics, which we complement with advanced graphs more able to represent the links between scholarly objects (be it publications, universities, researchers, funders and so on). These flow diagrams (heatmaps, chord diagrams and networks) are the opportunity to get an overview of the problem and dig deeper in it. The chapter finally mentions the tools and software most often used in bibliometrics visualization.
