This video shows how bad performance looks like in real-time line data visualization. The data visualization application is a refreshing (60 Hz refresh rate) line chart with up to 250000 data points.
The video shows several different JavaScript charts visualizing the same data* with mostly similar style configurations. Bad performance can be easily identified by visual choppiness in the updating of data.
*Weaker charts are using smaller amounts of data.
