Seaborn is biased towards statistical plot, especially linear plot, which is easy to use and simple. The entire syntax layer of seaborn will also be much simpler, and it looks nice to draw a picture without any modification. However, the drawing method is limited and not flexible enough.
Bokeh uses js

Summarize and calculate descriptive statistics, process missing data, hierarchical indexes

Date and time data types and tools (date processing easy to fly)

The first academic paper in my life was submitted yesterday. Funny is the last change of the result also forgot to cut the picture. The boss said that my carelessness will certainly make me pour a lot of mold, I thought. But there is really no motivation when writing a paper, there is no meaning to change. I want to program every day, but I didn't do it at all.See how many books and courses you would like to see but not read (can you read them on a laptop?) ):
