To create a real-time visualization dashboard that displays clients on a map, use Live View and WebSocket APIs. The 'Live View' feature in Juniper Mist provides a graphical, interactive map view of clients (devices) and assets as they move through a site, with location data updated in real time. The Juniper Mist WebSocket API enables developers and integrators to subscribe to client location topics and stream position data directly to custom dashboards. According to the documentation: 'WebSockets open a bidirectional communication session for sending and receiving real-time event-driven responses... Useful in circumstances where you want to avoid browser refreshes and display real-time location data.' Combining these allows you to build a dashboard showing live client positioning, as seen in sample dashboards and integration guides for Mist.
