# SVG

How to make **svg** images instead of rasterpng files ?

Using **draw** package ( interface to Gnuplot) :

"This terminal is not directly supported by draw, but you can use the 'user_preamble' option to force output in svg format.

Here is an example:

draw2d(explicit(exp(x)-1,x,-1,1),user_preamble=["set terminal svg","set out 'mysvg.svg'"]);

But you have to add by hand svg at the end of the file. For some reason this mark is sent to the console and not to the svg file, at least for me." (Mario Rodriguez proposition in discussion about discrete dynamical system on the Maxima mailing list)

## Examples

Here is png image and its svg version.
