Svg A Path. S smooth curveto. Path commands are instructions that define a path to be drawn.
Open the svg using Inkscape. All the basic shapes can be created with a path element. T smooth quadratic Bézier curveto.
I was happy to see that SVG has a native element textPath to accomplish exactly that without having to resolve to using an image instead.
Inkscape is a svg editor it is a bit like Illustrator but as it is built specifically for svg it handles it way better. The SVG element is the generic element to define a shape. The syntax of path data is concise in order to allow for minimal file size and efficient downloads since many SVG files will be dominated by their path data. In case their lower case commands are used then relative path.
