In Polinode, you can compute 20 distinct network metrics, encompassing areas such as centrality, betweenness, closeness, and community structure, among others. Additionally, the calculated metrics are available for download, enhancing their usability. Central to Polinode's functionality is the ability to share both networks and surveys with collaborators. The platform operates entirely in the browser, eliminating the need for any downloads, which simplifies the process of inviting others with customizable permissions. We prioritize the security of your data significantly; within Polinode, you can choose to keep networks private or public, and we utilize top-tier enterprise infrastructure to safeguard your sensitive information. Designed for scalability, Polinode efficiently handles the upload of networks containing tens of thousands of nodes while also facilitating the computation of complex metrics or conducting surveys that engage tens of thousands of participants. This flexibility makes Polinode an invaluable tool for researchers and organizations alike.
