What is a bokeh model?

One of the central design principals of Bokeh is that, regardless of how the plot creation code is spelled in Python (or other languages), the result is an object graph that encompasses all the visual and data aspects of the scene. The low-level objects that comprise a Bokeh scene graph are called Models.

Is bokeh better than Matplotlib?

Matplotlib can create any plot because it is a low-level visualization library. Bokeh can be both used as a high-level or low-level interface; thus, it can create many sophisticated plots that Matplotlib creates but with fewer lines of code and higher resolution. Bokeh also makes it really easy to link between plots.

What does bokeh mean in terms of photography?

When a depth of field is deep, both the subject, the foreground, and the background are in focus. Bokeh is the characteristic and quality of the blur produced by shallow depths of field. Fun fact, ‘bokeh’ is a Japanese word which directly translates to “blur”!

Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas. However, bokeh is not limited to highlights; blur occurs in all regions of an image which are outside the depth of field .
