Draws circles, ellipses, rectangles, polygons, stars, lines, arrows, waves, seeded organic blobs (the same seed always gives the same blob) or your own path data, with fill, stroke, rotation and padding. Shape mode exports a standalone SVG, pattern mode wraps it in a repeating <pattern> tile, icon mode produces a 24×24 currentColor outline. The secondary pane holds an encoded data URI for CSS and <img>; the preview renders the SVG on dark and light surfaces. Everything runs locally.
