You can also set the .src of your Vector Images via Velo to be the SVG string that starts with <svg …
That means you can run something like:
//Where mySVGComponent is a Vector shape or Image
$w("#mySVGComponent").src = '<svg id="chart_SVG" width="900" height="600" role="img" xmlns="http://www.w3.org/2000/svg"></svg>'
This also means that you can store the SVG strings as text fields within your database.
