I’ve seen a number of requests for violin plots in Bokeh. I needed a violin plot for a work project, so I built one. I built it as a simple function with a minimum of one argument (a data series). The function returns a Bokeh figure object.
You can get the code (including complete example and test data) here: CodeExamples/Violin at master · MikeWoodward/CodeExamples · GitHub
Here’s a picture of the violin plot.
