Summary

In this chapter, we've shown you different ways of working with streaming data. We started by showing the concepts of creating streaming graphs by creating a simple line graph that shows real-time information based on mouse movements. After that, we connected to a simple WebSocket server which provided us with ECG and respiratory information, and streamed the received data directly to two line graphs. We also provided a streaming alternative to area charts in the form of a streamgraph. With a streamgraph, we can create a visually pleasing visualization of multiple streams of streaming data. Finally, we connected to a publicly available WebSocket server and used the information from that server to update a map in real time. In the next chapter, we're going to look into two final visualization approaches using Voronoi diagrams and heatmaps.
