SVG in Lumira

I built an SVG image with proper id's so that I can modify it with d3.js using select("#id"). But the problem is I am not able to insert the SVG code into the lumira extension.

The SVG element contains text and this is what I want to modify with d3.js.

But without actually adding the svg code, I cannot modify it with d3.js

Is it correct to say that I would use something like require.js?

Any hints?

thanks!
