If you watch the video, one of the creators explains this point, which makes datashader different from, say, Bokeh. (Pipeline explained around 7:20 in the video) https://www.youtube.com/watch?v=6m3CFbKmK_c https://www.youtube.com/watch?v=6m3CFbKmK_c D3 and Bokeh and other web-based visualization tools, in general, plot HTML or CSS primitives to the browser. This approach works great for smaller datasets, but doesn't scale to millions/billions. Datashader aggregates (accumulates) graphical representations of data into images, then provides a way to get those to the browser and work well with the other libraries. That high level description leaves out 95% of the critical practical details of visualization, which the creators of datashader handle.
