You may know that it's possible to create awesome Vega charts with (or without) vincent. If you're willing to put one inside a popup, it's possible thanks to folium.Vega.
import json
import numpy as np
import vincent
scatter_points = {
'x': np.random.uniform(size=(100,)),
'y': np.random.uniform(size=(100,)),
}
# Let's create the vincent chart.
scatter_chart = vincent.Scatter(scatter_points,
iter_idx='x',
width=600,
height=300)
# Let's convert it to JSON.
scatter_json = scatter_chart.to_json()
# Let's convert it to dict.
scatter_dict = json.loads(scatter_json)
m = folium.Map([43, -100], zoom_start=4)
# Let's create a Vega popup based on scatter_chart.
popup = folium.Popup(max_width=800)
folium.Vega(scatter_chart, height=350, width=650).add_to(popup)
folium.Marker([30, -120], popup=popup).add_to(m)
# Let's create a Vega popup based on scatter_json.
popup = folium.Popup(max_width=800)
folium.Vega(scatter_json, height=350, width=650).add_to(popup)
folium.Marker([30, -100], popup=popup).add_to(m)
# Let's create a Vega popup based on scatter_dict.
popup = folium.Popup(max_width=800)
folium.Vega(scatter_dict, height=350, width=650).add_to(popup)
folium.Marker([30, -80], popup=popup).add_to(m)
m.save(os.path.join('results', 'vega_popups.html'))

Now, you can put any HTML code inside of a Popup, thaks to the IFrame object.
import branca
m = folium.Map([43, -100], zoom_start=4)
html = """
<h1> This is a big popup</h1><br>
With a few lines of code...
<p>
<code>
from numpy import *<br>
exp(-2*pi)
</code>
</p>
"""
iframe = branca.element.IFrame(html=html, width=500, height=300)
popup = folium.Popup(iframe, max_width=2650)
folium.Marker([30, -100], popup=popup).add_to(m)
m.save(os.path.join('results', 'html_popups.html'))
m
Note that you can put another Figure into an IFrame ; this should let you do stange things...
# Let's create a Figure, with a map inside.
f = branca.element.Figure()
folium.Map([-25, 150], zoom_start=3).add_to(f)
# Let's put the figure into an IFrame.
iframe = branca.element.IFrame(width=500, height=300)
f.add_to(iframe)
# Let's put the IFrame in a Popup
popup = folium.Popup(iframe, max_width=2650)
# Let's create another map.
m = folium.Map([43, -100], zoom_start=4)
# Let's put the Popup on a marker, in the second map.
folium.Marker([30, -100], popup=popup).add_to(m)
# We get a map in a Popup. Not really useful, but powerful.
m.save(os.path.join('results', 'map_popups.html'))
