[Piaskun]

Please add option to save created diagram as SVG or JPG - very useful for documentation.

@Piaskun Thanks for raising this, I am also using streamlit flow but facing the same issue that right now there is no way to download the generated diagram.

I tried using custom javascript like html2Canvas etc but that dosent really work, because the quality of image is extremely low with these javascript options. It would be really better if streamlit-flow can provide something here by default
