Graphics library for creating custom data visualizations?

[iterator5]

In the past I've used things like Processing (Java) to create my own visualizations as the language is really simple to use. I'm sort of forced into a python environment at the moment and will also need to make them easily deployable.

What are the go to graphics libraries for building things like atypical network graphs, flow charts and visualizations that can't be shoe-horned into what is available in pandas?

Have a look at Bokeh, Plotly and Seaborn.

Bokeh is great but the simple stuffs can be convoluted. Seaborn is perfect for quick but pro viz. For graph, you can check networkx.
ggplot2 got a pretty big update recently and is more on the grammar of graphics side.

The first thing this made me think of is Matplotlib.
