    Tksvg is wired to look for viewbox property in order to work.
    Some svg files do not contain this piece of information. So the package
    is unable to process such files.

    However, the width/height information is always present. I would suggest turning this into a default viewbox in case it is missing. Doing this
    simple change does load previously unloadable svg files.

    I cannot confirm that tksvg refuses to load SVG files missing the
    viewBox attribute.

    Thanks, Csaba, for answering.

    Yes, tksvg uses nanosvg which implements a restricted set of the svg
    features:

    https://github.com/memononen/nanosvg

    You may also look to the wiki page how to deal with the restrictions:

    https://wiki.tcl-lang.org/page/SVG

    It opens an universe for Tk and is still limited in features and Tk
    integration (photo image).

    Any comment to improve it is welcomed !

    Take care,
    Harald
