Custom fonts and plot quality with ggplot on Windows

Graphics devices are weird, and operating systems are even weirder. If you are a Mac of Linux user, lucky you, you can go on your merry way! But if you’re a Windows user and you’ve ever screamed at your computer “Why the #&*$ wont my fonts work!?!?” or “Why are my plots so &#**ing pixelated!?!”, then read on. Note this is accurate as of May 2019. There is a lot of development happening on ggplot and graphics in R, courtesy of Thomas Lin Pederson and the rest of the ggplot team.

Orbital glyphs, part 1 (12 Months of aRt, April)

Welcome to my latest aRt project, which is very much a work-in-progress. I usually try to wrap things up in a nice bow before posting them, but this one was just too big for that, so I decided to split it over two months. This is part 1, in which I define a base algorithm for drawing various types of glyphs. I honestly don’t know what to call these, they started out with the idea of “orbits” and then evolved into something more like summoning circles.

I made the base graphic in R, and applied stylings to the SVG using manual editing and Inkscape. I got several questions about how I made it, so here’s the story from concept to final design. Concept From first looking at the DVS challenge data, I knew I would make a timeline.
