The importance of effective coordination between medical institutions is emerging in the treatment process for various diseases. For example, EVT (i.e., Endovascular thrombectomy) raised the demand for close coordination between medical centers for stroke patients. Despite the effective treatment prognosis, it is challenging to introduce EVT to all hospitals due to the cost and personnel limitations. To this end, several previous studies have inferred a network based on patient transfer data between hospitals and attempted visual analysis along with quantitative analysis of the network. However, the majority of prior work relied on variants of node-link diagrams for visual analysis. As the number of hospitals grows, such visualization could suffer from visual clutter, and the data could reveal additional information with other visual representations. In this paper, we propose effective visualization methods according to the data type and analysis purpose based on previous studies on network visualization.
