各SectionにBokehグラフA,Bがぶらさがって、タブっぽく表示切替が可能。

コード

グラフデータ用意

from bokeh.plotting import figure
from bokeh.embed import components
from bokeh.resources import INLINE

# Define section and tab identifiers
sections = ["X", "Y", "Z"]
tabs = ["A", "B"]

# Create figures and store components
contents = {}
for sec in sections:
    for tab in tabs:
        key = f"{sec}{tab}"
        fig = figure(title=f"Figure {key}")
        fig.scatter([1, 2, 3], [ord(sec), ord(tab), ord(sec) + ord(tab)], size=10)
        script, div = components(fig)
        contents[key] = {"script": script, "div": div}
