UPDATE: I just noticed, that this is only applied when browser is refreshed after initial visit.
This code imports a font (from a url) that is applied to holoview’s gridmatrix and hv.table:
import bokeh
from bokeh.themes.theme import Theme
from bokeh.sampledata.iris import flowers
import panel as pn
import holoviews as hv
from holoviews.operation import gridmatrix
FONT = "source sans pro"

iris_ds = hv.Dataset(flowers, kdims=['sepal_length','sepal_width','petal_length','petal_width'])
grid = gridmatrix(iris_ds).opts(title='Flowers - Block #123')
table = hv.Table(iris_ds)
pn.Row((grid + table)).servable(title='Demo font loading')
Although subtle in appearance compared to default font, compare the ‘l’ in Flowers and ‘g’ in length. Source sans pro is shown in bottom portion of image.
