SVG support

Is your feature request related to a problem? Please describe the problem.

I want a way to output svg graphics in Python. I’m not the only one!

Describe the solution you’d like

I would love for st.write(...) to support an existing svg python library like

• svgwrite
• svglib
• CairoSVG (Never tried these, so not sure which is good, but we should pick the best / most widely used one.)

Describe alternatives you’ve considered

We could also look to see if Jupyter supports SVG and which libraries they’re using.

A few additional notes from offline conversations:

• It would be great if we could autodetect the format parameter too.
• These should all be viable:

st.image(url_to_svg, format="svg")
st.image(svg_string, format="svg")
st.image(stringio_with_svg, format="svg")  # (So it supports files)

@drorata : I believe that for that case you’d have to first open the file with Python’s open() function, then pass it into st.image().

I hope you and your loved ones are safe and well! ✌️
