💖 vector_graphical(1grass) — the graphical index of GRASS tools 💖

okay bestie, so vector_graphical, from the GRASS User's Manual, section (1grass) — it's literally the ✨graphical index✨ of GRASS tools, and this part is the entire vector family. Every single tool, every single one-liner, no skips, no cap. Let's go 🦋

🎀 a lil note about the styling 🎀

yeah so the actual page ships with this stylesheet, and bc we keep everything, here it is verbatim — it's what makes the icons pretty in a browser, okay 💅

.img-list { margin: 0; padding: 0; list-style-type: none; } .img-list li {
padding: 5px; overflow: auto; } .img-list li:hover { background-color: #eee; }
.img-list li a { color: initial; text-decoration: none; display: block; }
.img-list li img { width: 10%; float: left; margin: 0 15px 0 0; background:
white; object-fit: scale-down; } .img-list li img.default-img { max-height:
5ex; background-color: var(--gs-primary-color); padding: 5px; } .img-list li
.desc { margin: 0px; } .img-list li .name { margin: 5px; display: block; color:
