Hi @karolzak

Thanks for your answer.

This change requires urllib package (to convert the svg file in a less ambiguous way, otherwise the svg code was messing with the html). I did minimal changes to one function without changing the user functions, as i didn't want to mess with the rest of the package yet.

Please tell me if you want me to do it (i'm really afraid to do something wrong as it's the first time i do a pull request :)).

Best,

Mikael

Edit: sorry that all the tests failed, i overlooked a lot of things it seems
