r - Increasing all font sizes in ggvis -


i'm looking ggvis equivalent of ggplot2 function call: theme(text=element_text(size=20))

let's take simple graph made ggvis:

mtcars %>%    add_rownames() %>%    ggvis(~mpg, ~disp, fill = ~vs) %>%    layer_text(text := ~rowname)

enter image description here

there font sizes axis titles, tick labels, text layer, legend title, , legend tick labels. in svg, of these font sizes set in element:

here, example, 1 of labels in legend:

<text x="3" y="36" text-anchor="start" dy=".9em" style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 10px; line-height: normal; font-family: sans-serif; fill: #000000; opacity: 1;">0.0</text>

notice font-size: 10px;. prevents me modifying font size via css in page svg embedded.

is there global way of stripping fontsizes elements, can use css? or there way increase fontsizes via ggvis?
