Here we directly give the code for data preview and visual design , Some of the codes in the figure will be explained in detail , The data preview is as follows ：
Custom color Dictionary year_color The construction code is as follows ：
color = ("#51C1C8", "#E96279", "#44A2D6", "#536D84",
"#51C1C8", "#E96279", "#44A2D6", "#536D84")
year = artist_01.index.to_list()
year_color = dict(zip(year,color))
year_color
The visualization code is as follows ：
plt.style.use('fivethirtyeight')
fig,ax = plt.subplots(figsize=(8,4),dpi=200,fac
