maybe a little off topic, but i really wonder how you draw graph in the paper with code

i've read this paper and T0 paper, beautiful chart(though there are a lot authors of T0 paper, i bet it's you made charts in T0 paper right? cause charts in this paper and T0 paper have the same style, and it's beautiful). I notice that these awsome charts are drawed by code, but I didn't find correspond code in this repo. Did i miss something? I'm really curious about how you draw these pictures.
