Data science is all about finding insights in large data sets. In many cases, these insights are easier to find, or at least more persuasive, when they are visualized. A number of graphics libraries exist in the data-science world, some of which are written in Python. In this talk, Brian Van de Ven introduces Bokeh, a visualization library for Python that works with other elements of the SciPy stack to create beautiful charts and graphs.  Bokeh goes further than other libraries, in that it not only produces static images, but also dynamic visualizations in which someone can explore the data.
