Add option to create svg image with wordcloud_cli #693
Description
Description
I'd like to create an svg image with wordcloud_cli, which is currently not possible.
Steps/Code to Reproduce
--imagefile only references PNG image:
❯ wordcloud_cli --help | grep imagefile
[--imagefile file] [--fontfile path] [--mask file]
--imagefile file file the completed PNG image should be written to
Expected Results
wordcloud_cli should produce images based on the file extension. i.e. if I use --imagefile img.svg, a SVG should get produced.
Actual Results
❯ wordcloud_cli --imagefile img.svg --mask examples/alice_mask.png --text examples/constitution.txt
❯ file img.svg
img.svg: PNG image data, 900 x 900, 8-bit/color RGB, non-interlaced
