This looks good on desktop and mobile. Question - how does one configure which font the svgs use? Will it just default to Arial in the future or do blog authors have to specify?

[sgratzl]

I haven't found a way to proper configure/specify with font to use, R seems to use https://www.rdocumentation.org/packages/gdtools/versions/0.1.1/topics/match_family to determine which font family to use depending on availability. The mscorefonts ensures that Arial is available.

[tildechris]

So in this case, you've made sure that Arial is available and when you regenerated the svgs, match_family decided that Arial is a better choice than Dejavu sans?

[sgratzl]

The problem is that there are several layers on top of each other, blogdown -> R -> svglite device and I don't know a way to specify options for the lowest one. It seems like Arial is the default sans font (see also https://svglite.r-lib.org/articles/fonts.html). It wasn't used before since in a docker environment there are no fonts at all installed by default. The Anaconda environment ensures that we have the Arial font now.

Thanks for the background. LGTM.
