Gilles CollingStarted learning Affinity Designer last week for graphical abstracts. I'm a second year PhD student and I have no idea what I'm doing in a design tool. But it's fun. One-time purchase, no subscription, no telemetry. If you make graphical abstracts for your papers, what do you use? #AcademicTwitter #rstats

@GillesColling I use inkscape, considered the open source version of Adobe Illustrator. There are lots of tutorials and a great community around it.
