There are a lot of smart people that like Python.  There are a lot of smart people that like R too.  Bokeh is designed to be useful from both R and Python (and other languages as well).<p>Here is a recent presentation showing Bokeh (from Python) along with data-shading to visualize billions of points quickly:  <a href="http:&#x2F;&#x2F;www.slideshare.net&#x2F;continuumio&#x2F;visualizing-billions-of-data-points-doing-it-right" rel="nofollow">http:&#x2F;&#x2F;www.slideshare.net&#x2F;continuumio&#x2F;visualizing-billions-o...</a><p>Here is another presentation showing integration of Bokeh with R to visualize geographical data from another group: <a href="http:&#x2F;&#x2F;ryanhafen.com&#x2F;blog&#x2F;rbokeh-gmap" rel="nofollow">http:&#x2F;&#x2F;ryanhafen.com&#x2F;blog&#x2F;rbokeh-gmap</a><p>0.11 and above releases of Bokeh contain a server that provides a very nice application model that can be synchronized between browser and server for allowing data scientists to build interactive plotting-based applications in the browser.    Here are some simple examples of that:  <a href="http:&#x2F;&#x2F;demo.bokehplots.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;demo.bokehplots.com&#x2F;</a>
