Please follow the instructions on the Github repo if you want to reproduce the specific examples on this website, or the ones at PyViz.org if you want to try out Datashader together with related plotting tools. The video Visualizing Billions of Points of Data (and its slides ) from a February 2016 one-hour talk first introducing Datashader are also available, but do not cover more recent extensions to the library. The source code for datashader is maintained at our Github site, and is documented using the API link on this page.
