Construct a new Labelfont object
Sets the font used for labeling the contour levels. The default
color comes from the lines, if shown. The default family and

Parameters
----------
arg
dict of properties compatible with this constructor or
an instance of :class:`plotly.graph_objs.histogram2dcon
tour.contours.Labelfont`
color
family
HTML font family - the typeface that will be applied by
the web browser. The web browser will only be able to
apply a font if it is available on the system which it
operates. Provide multiple font families, separated by
commas, to indicate the preference in which to apply
fonts if they aren't available on the system. The
plotly service (at https://plot.ly or on-premise)
generates images on a server, where only a select
number of fonts are installed and supported. These
include "Arial", "Balto", "Courier New", "Droid Sans",,
"Droid Serif", "Droid Sans Mono", "Gravitas One", "Old
Standard TT", "Open Sans", "Overpass", "PT Sans
Narrow", "Raleway", "Times New Roman".
