You can certainly create plots like that with bokeh. Please see the annular wedge glyph in the documentation Annular Wedge.
With compatible choices for the locations (x,y), inner-radii, outer-radii, start-angles, and stop-angles for multiple wedges such a plot can be created with the existing bokeh engine. Presumably, the interactions to select a sub-region and generate a new sunburst or modify the existing one can be done with some work via callbacks.
Here’s a screen-capture of something that I implemented a while back for an interactive radial equalizer. The use-case is quite different, but the general visualization is qualitatively similar.
