The svg driver produces SVG (Scalable Vector Graphics) files that are compliant with the SVG 1.1 specification as defined here. This driver has no external library dependencies. The driver is unicode enabled. As SVG is just an XML based graphics language, the visual quality of the resulting plot (e.g., antialiasing of text and graphics, unicode system font availability, and handling of complex text layout issues) will depend on the SVG rendering engine that is used.
