Understanding SVG Path Commands Changed How I Think About Vector Graphics

The SVG <path> element is the most powerful and most intimidating element in the SVG spec. A single d attribute can describe any shape -- circles, curves, complex illustrations, font glyphs -- using a compact string of commands and coordinates. But reading and editing that string by hand feels like decoding machine language. <path d= "M10 80 C40 10, 65 10, 95 80 S150 150, 180 80" /> Until you understand the command vocabulary, that is meaningless. Once you do, it becomes precise and elegant. There are only 10 commands to learn. The command vocabulary Every path is a sequence of commands. Uppercase commands use absolute coordinates. Lowercase use relative coordinates (offsets from the current position). M/m (Move To): Move the pen to a point without drawing. Every path starts with M. L/l (Line To): Draw a straight line from the current position to the target. H/h (Horizontal Line): Draw a horizontal line. Only needs an x-coordinate. V/v (Vertical Line): Draw a vertical line. Only needs
