SVG vector graphic too big

Hey guys,

quick question: I want to create an interactive graphic using SVG and javascript. So far so good. I created the graphic in Visio and wanted to insert it into the HTML part of the question, but apparently it exceeds the maximum amount of characters "You have exceeded the size limit of 20000 characters. Please reduce your text.". However, smaller SVGs work. Also, I cannot upload SVGs as graphics. Is there a workaround I'm not aware of?

Thanks a lot for your help!
Steven
